Poor service..

What a terrible, disappointing experience I've had with MTN in hammarsdale junction mall. Theres no service at all, lack of knowledge. On Sunday the 2nd of may I visited an MTN branch in hammarsdale to do a Sim swap for a contract, and of course as usual the system went offline, I wasn't assisted and was told to come the next day, which I did. Again the system was offline I waited until the system went online, I was assisted and they told me the Sim swap was successful and I should wait for 24 hours then the aim card should be working fine. The next day I waited until 24 hours ended but still the sim card wasn't working. Tried to phone the call centre from 6pm afternoon and was able to get through to speak to someone by 9:30pm, and that's when I was told the sin swap was never done at all, after paying R115 for the new sim card. Today I went back to ask them what had heppened and again they can't check on anything because the system is offline. It's so disgusting and annoying and frastrating that I had to wait for 2 months to get the new phone and do the sim swap and now this. The level of professionalism and service is greatly poor. And not to mention the fact that stuff members needs training you...
