MTN is absolutely useless

I am a VIP package holder and been with MTN for over 20 years. I am trying to do a simple phone upgrade. I went into the Fourways store, and the staff could not help because as always, the MTN system was offline. They promised to call me back, its been a month now and am still waiting for that call . Then I tried the Sandton store, whereby you need to get a ticket to be seen and helped (great customer service , the genius who came up with this), after waiting 45 minutes to be seen , there was a problem with the ticketing, and the store clerk told me il have to start all over again with waiting another probable hour? Remembering I am on the VIP package of which I have paid hundreds of thousands over the last 20 years. Finally with no where else to turn I called their call centre (this was enough to drive anyone to Vodacom or Cell C). Firstly as per always with MTN their systems are down, secondly once I got hold of someone I was put through to 'someone who could help me', this someone was a big large empty hole of music, that played for 20 minutes while I waited on the line, only to be cut off after 20 minutes. After trying to call for a 4th time I was put on hold and then I was delighted by not having music played to me but hearing the foul mouth of the MTN call centre staff talk, whereby their language was absolutely inspiring , great staff MTN every second word was the 'f' bomb while I was waiting patiently on the line. MTN I'm done and ready to move after 20 years of loyalty. Vodacom or cell C if you want a vip customer with 20 years loyalty and is simply looking for an apple X upgrade, please contact me or respond. MTN executives, while you enjoy your over inflated salaries and bonuses, remember who were the loyal paying customers to get you those over inflated bonuses over the last 20 years. MTN , you and your useless, unapologetic and unhelpful staff are a disgrace to the term 'South African' business. The sad thing is after this nothing will change and MTN will be happy to see another quality client lost. regards Brandon Garbutt- Extremely angry client
