A dad-of-four claims Scottish Power left his family without heating or hot water for days on end.
NHS worker Jason Milligan arrived home from work on Friday to discover that his gas supply had been cut off - leaving his family, including his disabled daughter, without central heating.
But when he contacted Scottish Power to discuss the issue, he says the supplier denied being responsible for his gas supply despite issuing him with bills.
Speaking to Edinburgh Live, Jason said: "I work as an NHS porter and finished my work last night, picked my kids up and as soon as I got in the house I noticed there was no gas.
"I checked the meter and it was out, so I pressed reset and it didn't work.
"My meter is a direct debit so everything is always paid.
"I got onto Scottish Power and phoned eleven numbers in total and they all kept redirecting me back to the same closed line.
"I eventually got through to a line that said 'if you have an emergency then press one.'
"A guy answered and said they wouldn't be able to attend until Monday.
"So I said fine and I got in touch with my local authority and they came out last night and gave me two emergency heaters, but I still have no gas, I have no hot water and I still have my four kids in the house.
"My daughter has medical issues so this situation can't go on. I have just phoned Scottish Power this morning and spoke to someone and they said they don't even supply me."
Jason, from Wester Hailes in Edinburgh, says Scottish Power have arranged for him to call back and speak to someone on Monday morning.
But he is now faced with having to stay at home with his children in a freezing cold flat with no hot water for the rest of the weekend, despite paying £67 a month to the energy giant.
The dad only recently moved into the property and had issues with the energy firm from the get-go when the wrong address began to appear on his bills.
He continued: "Now, I moved in this property in November and have been paying Scottish Power £67 per month by direct debit for my gas so I asked him about that.
"He explained to me that it was a company called E-gas who are my provider. So, I phoned them up and they said no, they didn't provide my energy and put me onto Utilita Energy.
"I phoned Utilita Energy and they don't know anything about the box, and said it must be run by a business.
"I got the keys for this place on November 23rd and the minute I got in there I went with Scottish Power.
"I got a welcome pack from them and downloaded the app.
"However, it started showing up on the gas section as different address in this area. That was still the case right up until last night when this happened.
"I am just going round in circles with Scottish Power now, have sent them emails with screenshots proving my payment, or screenshots of readings from my gas meter, but it doesn't make any difference."
Jason even says that Scottish Power had previously agreed to a 24-hour call out because he had a disabled child.
He summed up: "Do you know, when I moved in I just went with Scottish Power rather than any other provider.
"I've been talking to Scottish Power now for weeks, with the address thing, and now this issue with having no gas.
"Do you know what the funny thing is? When you have a complaint or an energy emergency it takes ages to get an answer or response but when you are phoning them to make a payment they take your call right away.
"So as it stands right now, I have no gas, I don't know who is my provider and the best Scottish Power are saying they can do for me is to arrange another phone call for Monday morning, when I am meant to be working.
"We are all freezing here, all we have are two tiny heaters to heat all of us.
"Scottish Power know that one of my daughters is disabled and had previously told me that this covers me for a 24-hour call out but it seems to be making no difference."
A Scottish Power spokesperson insisted that the firm did not supply Jason's gas but has committed to helping him resolve the issue.
They said: "We currently do not supply Mr Milligan's gas.
"We have tried to make contact with the actual supplier to help get his supply restored.
"We will continue to follow up on this and do all we can to help.
"However, we have no way of restoring his gas supply when it is the responsibility of another supplier."
