Help please

So I left O2 two months ago. Called paid off my remaining balance and told them I was leaving as I found a better deal elsewhere. 

2 months on they owe me money but rather than refund it they keep sending me a bill that is in credit and tell me they will role it forward to next month. I have no products with them, no phone number that is on their network

I have tried to contact O2 directly but it seems unless I call from an O2 number I can't contact them? Why can't I email them? Why do I even have to ask for my own money to be refunded?
