I WILL NEVER ADVISE ANYONE TO GET A CELL C ACCOUNT!

I have 2 accounts with Cell C i have been making payment but the balance is not coming down. When i call to find out about my account they keep sending the invoices for the wrong account and can not pick up my outstanding account in question. Now i am getting collection emails and can not get hold of the department and i get transferred over and over to different people to "HELP" but still i can not get anyone to help?? I only have one account on my ID number? I WILL NEVER ADVISE ANYONE TO GET A CELL C ACCOUNT!
