TERRIBLE SERVICE

Trying to upgrade my cellphone contract since 6th Aug 2024. Got returned due to incorrect contact number, which was supply to MTN on my online application. On the 13th Aug I had to re apply which I did and inform them about my number that must change. After numerous calls and emails from my side, I still have no joy from MTN or DSV. They do not even reply to my emails or get back to me with feedback. I have never had such issues before.
