Carphonewarehouse

Terrible company

I had a mobile phone contract with Carphonewarehouse for nearly 5 years and when I tried to renew my contract with them they told me that I failed their security check! I was then told to go in to a store to get my new contract and phone. I went in to the store and went through their security check to be told that I failed it again. So I went straight to the 3 mobile store and signed up for a contract directly with them.
When I received my last bill it had a credit balance on it but I never received the money back in my bank account. It didn't say anywhere on the bill how I could get the money back. I emailed them and they said they can arrange for the money to be paid back onto my debit card if I called their customer service. So I called their customer service and the agent told me he could send me a cheque but couldn't refund it onto my debit card.
I then spoke to their complaints department and had a painful conversation with them where they were reluctant to even apologise!
