I cancelled my youngest child's contract in Jan 25 and ported the number to a new network. I believed this was the end of this contract and I followed the advice and didn't cancel the direct debit straight away. I have 2 other contracts with ID mobile on direct debit so when I cancelled the youngest child’s direct debit I hadn't noticed that it was still taking the payment amount from my account, despite it not being active. I have since received a Debt Collection Agency letter for unpaid bills but offering no other information. After many emails and queries and online chat conversations with ID mobile I discovered it was the contract I cancelled in Jan 25 that was the issue. The chat advisor has stated they cannot cancel this contract, so how do I do it then? The number doesn't exist anymore so I cannot use the app (again). Am I now forever stuck paying for a phone number that doesn't exist? The DCA used is no help, in fact they appear to be inept and cant seem to answer emails. Has anyone had this issue and how can I cancel a cancelled contract?
