No Resolve

I hate to do this but since last year September I have been struggling to get my credit and money back. I tried to buy an item online and it failed on my side. Now I am being billed for the item I tried to buy. Money has been deducted out of my account after I explained the situation. I contacted game and rcs multiple times to resolve the problem. No one is resolving my problem. Still they are contacting me everyday to pay my account and arrears. I am sorry but I refuse to pay for an error on the system and an item I never received. This utterly pathetic.
