A mum wants her daughter's £450 bus puss refunded because the pupil's bus is full almost every day, making her late for school.
Lara Hall, 13, has only been able to catch her Stagecoach 7.45am service to Canterbury Academy six times since the beginning of September.
The next bus isn't for another half an hour, meaning she consistently misses morning "mentoring" sessions, where pupils have the chance to catch-up with their tutor.
Her mum Linsey told KentOnline it made her daughter very anxious, and added the teen wasn't the only one affected by the ongoing issue.
"It's particularly bad for the Year 7s. They stand there just crying. They’re stressed about going to secondary school in the first place," the mobile hairdresser said.
She said other parents were also concerned.
Linsey is unable to give her daughter a lift as she needs to drive her youngest child to school before going to work.
She said Stagecoach should refund the annual £450 she paid for a Kent County Council Travel Saver bus pass, which gives pupils 50 per cent off fares.
"We are paying Stagecoach around £450 a year for a bus pass which is absolutely disgusting, as she's only managing to get on the bus to come home from school," she said.
"How can they have a conscience? They just don’t care, but they’ll happily take the money off us. It’s just not good enough - I'm at my wit's end.
Linsey said she had emailed Stagecoach on several occasions but nothing has been done.
A spokesman for Stagecoach said there were three buses to the Canterbury school which stop in the village of Boughton, where the family live, one at 7.25am, one at 7.45am, and one at 8.15am - all double deckers.
He added: "Although the 07.45 bus is a busy service, there is enough capacity overall to carry everyone who needs to travel. We're always happy to help advise our customers on the different options available and we are in communication with local schools to improve awareness of bus journey options for students travelling into Canterbury."
Linsey, however, insists more buses were needed.
It comes after Kent County Council agreed to cut funding for Stagecoach, which means there will actually be fewer buses on the road. A total of 38 services will be disappear in February.
Council leader Roger Gough said cutting the subsidies was necessary to balance the council's budget for this year.
Canterbury Academy Trust and Kent County Council have been approached for comment.
