MTN Business - Lost cause

About a month ago, I've requested MTN to migrate my paid up personal contract (Dual SIM Service) to my business account since the secondary number is primarily used for Business.

MTN in their wisdom, then cut the secondary number and done nothing to the primary number, resulting in me not having any service on both numbers for over 3 weeks.

Despite numerous calls and emails to their service rep @bongile Msent1 and their various service desks - This still have not been resolved causing me lost business customers as the line is "Not on the MTN network"
