Telkom suspends prepaid line without prior notification

I have been using my Telkom simcard for just over a year and never had any issues up until this morning when I was trying to check my airtime balance it could not connect. No issues continued my day when a client pitched at my place and asked why mu phone was off. I tried to make a call whereby upon my shock got a voice recording saying my number has been locked. Called customer service( waited 15 minutes on the line) and spoke to a rep which I cant recall her name. Explained my situation was placed on hold for another 10 minutes just to be told my number has been suspended due to it not being RICA'd. First of how can I be using the number for more then a year plus without it being registered. Did not receive notification of said plans to suspend my number. I have lost 4 clients today as its my business number and could not make payments to retailers as all is attached to said number. Please get back to me on an amicable way to get my number back
