Cancel my contract fetch your phone!!

My credit score was low because I never had credit. So to help my credit score I was able to take out a phone contract with Blue Label Connect. My debit order went off on the 27th of last month. The call Centre has called me everyday since the beginning of this month. I have emailed proof of debit gone off Time and time again' I have spoke to so many people seeing I get called EVERYDAY. YOU CLEARLY ALLOCATED MY DEBIT ORDER AGAINST SOMEONE ELSE'S NAME, AND YOU ****ED MY CREDIT up even more. All the call agents told me that they will fix the Issue yet they called me twice today already. Oh yes and taking this contract I was suppose to get 2gb free data and calls... Nothing never got that at all. I want you to cancel my contract and fetch your phone and I am telling you now let one more agent call me. The next call I want I dB someone calling me with the info I need. I want you to pull all recordings to my number and listen to them all especially how I was treated and spoken to on the phone from one of your agents when I asked to speak to a supervisor.... I was discussed and she had the cheek to put the phone down in my ear.
