Vodacom Recycles numbers and their customers becomes a secretaries

I just want thank Vodacom once again for the recycled number they gave me. Probably got this contract for 5 months now and still get about 2 calls a day for Mr. Oscar Dlamini. (I am not Oscar Dlamini). Potential customers, be very careful when taking a contract with Vodacom. They recycle old numbers and you as a new customer get calls all the time for people looking for someone else. I complained and complained, but Vodacom don't care. It will cost them less than R20 just to change my sim, but no. I willing pay the R20. Still the answer is no. That means I got about 18 months to go before I can cancel this contract.
