CELLPHONE NUMBER SOFT SUSPENDED

I migrated from contract to prepaid last week Thursday and I was informed the process will take 2 to 24hrs, but until to date mtn went ahead and suspended my number *** without informing me of anything. I have been in contact with their call center on a daily basis since Saturday but none can assist me to unlock my number. I cannot receive or make any out going calls, this is frustrating l am running a business and rely on my telephone communications, so a week without receiving or making contact make things really worse and am losing clients as they cannot get hold of me. Please assist urgently to sort this out, call center agent Nondumiso gave Ticket number ***
