DISGUSTING SERVICE AND A DONT CARE ATTITUDE

My Blackberry (9720) model is on the blink. Vodacom supp**** me with the phone. I can't make phone calls with my vodacom sim card,. The vodacom sim card however works in my older blackberry model. I was told over the phone by a vodacom technician that they are aware of the problem and all 9720 blackberrys had a problem which was being attended to and should be resolved within 24 hours. It has been nearly 3 weeks now and the problem is still not resolved. I visited the Vodacom shop at the Glen and told them about my problem and there reply was that i should either swop service providers and try an MTN sim card or i should buy another phone for R3000. I told them that i am disgusted with Vodacoms service and was told that i would have to drive to Midrand to hand my phone in for repairs at my own cost. I told them there is nothing wrong with the phone as it is compatible with any other sim card i.e Cell c or MTN so why should i pay for the cost and waste my time driving to Midrand. I am unfortunately locked into the contract for another year and have no other alternative but to continue with my old phone until the contract is up. I am very disgusted and dissappointed with vodacom.
