Upgrade wait over 3 days now to get my sim active

where to start, first MTN steels my money, I upgrade one of my numbers, now I have been with out a phone for 3 ****ing days, as it has still not been activated, I have call the support number countless times, to no avail , now I am trying to call customer care , not one any of number is it going through, get cut off straight after pressing Zero to speak to an consultant .... I tried all the menu options on 2 different numbers same result.<br> I find this absolutely poor, how can you have a line down for 3 days after an upgrade ... ***.. and every time after call support I am still no where, forced to now use a data line to make calls due to this pathetic service received by MTN. If my number is nit active within the next hour I will cancel every single contract with MTN and they can stuff it where sun does not shine
