Poor Service

I switched my contract from Cell C , due to reception problems, to Vodacom. The contract was immediately approved, but I had to wait almost TWO weeks for activation. Just over one month later, my phone is in for repairs. Apparently the microphone is broken on this new phone. When I took it in over the counter to the repairs division, I was immediately informed that that Samsung is problematic. Why do they keep selling it then. Do we deserve bad products we pay thousands of Rands for. I was promised a call the following day after assessment, but I was not contacted. When I phoned in, I was told that they had to get the part from Jhb, and it'll take over a week to get the part and they could not give me date for when the phone would be ready. They have no over-the-counter 'service', to look at settings, the phone must just be booked in. I am amazed at the disgusting service these huge companies offer and we are bound to them by contract. Shocking.
