Yodel customers say they have been hit with delays and disruption due to the courier's "technical issues".
Dozens of people took to social media on Tuesday morning to express concerns that they couldn't access the Yodel website or track their parcels. Some have even reported a "delay" in parcels they are expecting.
One person wrote on Twitter: "How are customers supposed to make contact if your website is down and you are not receiving incoming calls?" As another added: "This is shocking. No form of contact or response from this company."
