CELL C CUSTOMER SERVICE PATHETIC

My son got hold of my Contract Cell Phone SIM Card Acc Num:*** which I do not use and used the data which amounted to R3,321.74.The amount was due end of July 2015. When I discovered this I immediately contacted CELL C Accounts Department wanting to make an arrangement to settle this over a period of six months as I could not afford to PAY the whole amount and for the whole amount be debited from my account. I easily contacted the accounts department more then 5 times and every time was given a reference number and that they were gonna get back to me. Nobody came back to me until yesterday when I was emailed that if they should not get payment within 2 days my account will be handed over to their Intermediate Dep for action to be instituted against me for the recovery of the arrears.They are quick to hand over my account and and to make contact to demand their money.I have phoned ample times requesting to make arrangement with their accounts department to pay it off before the debit went off and was every time told that someone was gonna get back to me.I PHONED MORE THAN 5 TIMES.and NO RESPONSE.I am appalled at the customer service from CELL C.PATHETIC TO SAY THE LEAST!!!
