MTN going back on their word

On 25 May 2015 we app**** for upgrades on 2 of our contracts. Because of the strike, you could not dispatch phones and we were given the option to wait until the strike ends or do the upgrade now and start paying for something that we had no guarantee of date of delivery. We opted to wait. On 22 June I spoke to them again.<br> I was informed that the strike was still ongoing and you could still not dispatch phones. I was also informed that one of the packages we wanted had changed and was now more expensive. I complained about it. It was not my fault that the upgrades could not be done (will you pay for something and wait an indeterminable time for it?) and asked that Lungisi ask her supervisor to contact me. She phoned me back later the afternoon and I was informed that her supervisor said the original packages as we app**** for them will be honoured.<br> <br> This morning Lungi phoned me and informed me that the strike is now over and the upgrades can be processed. However, the prices have gone up again and the original prices will not be honoured. According to MTN Business prices can be raised at any time and they will not honour the app**** for packages.<br> <br> So much for loyalty...
