EXTREMELY BAD SERVICE

I visited Vodacom at Mall@Reds in Centurion today to complain about the fact that Vodacom still has not arranged with RAM couriers to collect the faulty Mecer laptop on contract as per Online department of Vodacom. When i contacted them in November to tell them it is faulty, not even switching on the gentleman assured me that the contract will be cancelled and i will not be billed. REALLY? Then why is the debit order going through my bank for a product which is broken, faulty, not working at all, plus it was supposed to be collected. It is 3 months later and still no response. Please dont tell me RAM cannot get hold of me because everyone gets hold of me. Unless the stupid idiots are not using my correct cell number which i have confirmed several times before. WHEN IS THIS GOING TO BE RECTIFIED? i INSIST THAT THIS CONTRACT BE CANCELLED WITH IMMEDIATE EFFECT AND THAT VODACOM PAYS BACK MY MONEY!!!!!!!!!!!! Anna at Vodacom store tried to contact Online department but apparently they are experiencing technical problems and could not take her call. It seems this will never be resolved. To debit my accounts for a faulty laptop that was supposed to be collected and contract should have been cancelled in my opinion is *****!!!!
