Loyal customer not satisfied

Hi, I recently did upgrades on 2 of my contracts that I have with Vodacom. I had to do a sim swap as the sim cards were different to the old ones. I called Vodacom on the 15th June and spoke to a girl called Nozipho. She did a sim swap on one of my other contracts as opposed to the number I was calling about. I was without a phone for over a week. Eventually called and my query was escalated and a guy by the name Lucian called me to try and reverse the sim swap which he did, but then my airtime was not returned which he said would be. He also said I should send an e-mail and my original query( which was to do the sim swap) would be sorted. It is now the 24th of June since this whole thing started and I am still not sorted. I have been calling and e-mailing Vodacom with no satisfaction. It is disappointing because I have been a loyal customer since 2004.At this rate I have no intentions of ever renewing any of my contracts with Vodacom. I am truly disappointed and this has been a huge inconvenience!
