I have been trying to cancel my account… I have been trying to cancel my account with three for several months. I left the UK several years ago and contacted them multiple times to cancel. I no longer have the SIM, don’t even know the old phone number and don’t have access to the old email. As such I am unable to be validated by an OTP to close the account. Despite being formally informed to close the account - three just won’t. I even closed the bank account t which finally prompted them to send an overdue payment letter to my old address which was kindly forwarded to me. I then again contacted three and spent 1hr trying to get them to close the account. And they won’t! What a disastrous company!!!
