First time customer, shocking service

I have ported my number to MTN thinking that they are a better service provider than other companies. But this has definitely been a mistake. I first went to MTN Greenstone Mall to find out someone has opened a profile in my name and I have never been a customer of MTN. I was told that they can't help and I need to go to home affairs. Luckily my wife is with MTN and I went to a store in Boksburg on Rietfontein Road. These ladies where extremely helpful and managed to update my details but cannot change the name on the profile. They have logged a call with head office but surprise they don't want good references or new business, as I am still waiting for it to be changed 3 weeks later. I am running on prepaid at the moment and this is costing me a fortune. Please think twice before moving.
