poor service

I want my services cancelled with immediate effect. when I opened the like i gave my banking details. but I got a message that they cant debit my account. That was ok then I made internet transfer. May was allocated, June was never allocated and July was never allocated. I have called 5 times for my June payment to be allocated and i was promised 5 times it will be allocated but it was never done. I have even sent my proof of payment but nothing has been done. Now my credit profile is affected while cellc open serve has my money. so i cant be doing this every month. i want to cancel my contract you you guys and find a company who is serious about servicing me. I know its a 24 month contract but i kept my side and paid but your side didn't allocate my payments. now my credit profile is affected when u got my money. so i am tired i want to cancel my contract before time and please come and get your equipment and i don't wanna owe anything because i kept my side and cellc didnt keep thier side. Thats a bridge of contract. I want out and i don't want to owe anything to cellc. I hope we can get into arrangement that i will be happy and we go our separate ways.
