INCORRECT SIM SWAP

I phoned Vodacom on 25 March to activate my upgrade nr, instead they did a sim swap on my cell nr, I have been struggling since then to get this reversed to that I can use my sim card again and get the new sim card activated with the upgraded nr, Not only am I phoning 082111 the whole time following up on when this will be done without a time frame but the only answer I get is it is still pending! This was not a mistake from my side but from Vodacom side and they fail to assist me timelessly on this. I have been with vodacom for many years and for the first time I am satisfied with their service!!!
