Fnb connect is a joke

Worst service. Did a sim port from Mtn to Fnb. Did everything by the book, mtn accepted the port and disconnected my sim, but the number was never ported. Everything on mtn side is good and all but with Fnb, they have no idea whats going on or why my number never ported. This was a very important number that i use for business that is now up in the air. Losing alot of business now up! Why are you in the sim business if you have no idea what you are doing. I will never buy a fnb sim again.
