Phone / simcard

In February 2015 I upgraded my contract. When I received the phone the screen was cracked. They collected the phone and send it back to me telling me that must have dropped the phone (which I most certainly did not). Being a client for about 20 years this was unacceptable but I thought what the hell let me just fix the screen. About a week after I received the phone with the broken screen someone from Autopage calls me and tell me that they have decided to replace the phone, honest as I am I told the operator that I have received my broke phone back without my simcard. After many emails back and forth I still don't have my simcard (they charged me for) and the phone is still not working. The last email I received in May reads as follows: Kindly be advised your query has been escalated for further assistance. Needless to say that up to date no further contact or any solution. I would like this contract to be cancelled or my simcard and a working phone.
