NO SERVICE NO ANSWER Call centre- hold for 1 hour

I am trying since last week to get through to the call centre. We waited for months to get the line moved. They moved the line to the new address on 29/4/15 (app**** in January 2015). Now we cannot put money on the phone. It is blocked. We could not put money on the prepaid phone for the whole time that we waited for the transfer.
