No response on on-line LTE Black November aplication.

Absolutely appalling service! Went on-line with Black Friday, app**** TWICE for a 100 + 100 gig LTE contract, proving that I am a current customer - 20 year old contract - the specials expired a week later with absolutely NO contact fro MTN. Had to eventually mail customer service, 9 emails later PLUS proof of my application email, waited for 12 days without response - Mailed again and again and only then got a reply. I had to once again prove that I app**** - had to again send the reply mail on the application, still no response. In the mean time I have lost out on the special????? I am now in the process of porting my number to another carrier and NO response from MTN.... They will lose a lot of business this way and considering their poor ratings it doesn't surprise me at all!!
