I want to disconnect from ID Mobile, giving the 30 day notice. I received an email today from debt collectors on behalf of ID Mobile saying I owe £15. I paid it. They told me the Sim-only account was started in 2018. I do not have the phone with the SIM-only card so I cannot get the code you send. I have no app account or anything.
Please contact me to disconnect. The debt collectors gave me the phone number attached to the Sim-only card. So at least I have that.
