I have received the sim card but am now trying to cancel via the myID website seeing as i can now register. But i get the following error message when trying to end mobile plan.
“Invalid Request, Validating the request has been failed with CMP6 details”
Please advise i feel like this is impossible with not being able to call a customer services line. Most other providers appear to be ok handling queries. I will not be happy if i am now debited for this. This is just to cancel a sim only plan within the cool off period. It shouldn’t be this difficult.
