Most *********** workers in S.A

I have two contracts with cel c and in March I phoned in and changed the banking details. The person that assisted me assured me that everything is 100% and I won't have any problems the then at the end of March only the one contract went off my new account and the other contract went of the old account. I phoned back in the lady said she is so sorry it's their mistake she will update the system and she sent me an sms with the banking details as well. And guess what still went of the old account. Phoned in again this time after a 30 min call with the agent this time trying to prove that I did phone in because the lady said I never phoned in. I had my sms as probe to show I actually did phone in yet again this lady would of arranged an immediate debit and change details THIS ALSO DIDN'T HAPPEN. SO WHO THE HE'LL CAN ASSIST ME IN CHANGING BANKING DETAILS!!!! AND WHO IS PAYING ALL THE BANK CHARGES?????? THIS SERVICE IS THE WORST I EVER RECEIVED NO WONDER YOU GUYS WANT TO PAY CLIENTS TO CANCEL THEIR CONTRACTS WITH THEIR CURRENT SERVICES PROVIDERS. HOPEFULLY THIS TIME SO PHONED THAT ACTUALLY HAS MATRIC AND KNOWS HOW TO WORK A COMPUTER SO PEED OFF CLIENT... DON'T WON'T WITH EXCUSES.
