Bad service

I walked into a telkom store today to upgrade my contract as its over 2 years now and the person tells me that my number is suspended, I told them it cant be because im still receiving and making calls, then I asked them why is that they respond with they dont know because they can see my account is up to date but its still suspended, I was so excited about upgrading to a new phone but now im thinking twice if dealing with telkom, il rather cancel my contract and go somewhere else
