Very Unhappy

Ive been trying to contact MTN on their customer car number (173) I go through all the voice prompts and make all the relevant selections-however when I have to go through to a \service champion"my call gets cut and this has been happening for over a month now. I sent a mail through with my contact number and all I got was a question asking if I was a contract or prepaid customer and its now been 3 days with no assistance. Ive been with MTN for over 16 years now and for the very 1st time I try to contact their customer care"
