Horrible Service from MTN...

I app**** to upgrade online on the 15th already. Digital is the future, right? No, wrong... Not with MTN! I still am having hustles & bustles even to this day after I even went to their Mall Of Africa MTN Store. Instead of getting the service I need & actually be contacted on my cellphone, they keep sending emails with differently requests to finalize my query. The most recent one, today, was when they sent an email with the ref. number they gave me on the subject line, ***, asking me how I would like to be assisted??? The audacity? I'm a paying customer since early 2000, I've had one number which I still use today. That should answer how LOYAL I have been to the brand. I've made countless upgrades over the years which went seamless. Why is this a MAMMOTH TASK, all of a sudden? And why hasn't Management called me like I asked SIMPHIWE yesterday at the call centre? Are they too busy for a loyal, premium paying customer like me? Should I cancel all my existing contracts & take my business somewhere else? Well, we can arrange that if service is so horribly poor!!!!!!!!
