3G FLLA Wi-Fi Phone no data top up

At the beginning of March we were contacted by Telkom and told landlines were being discontinued due to cable theft. We had the option of having a 3G FLLA WI-FI phone. Our contract would give us 2G data every month. The data ran out at the end of March we are now at the end of April, still no top up, no wi-fi. I have phoned, no help. I have logged a fault, got a ref number and 2 days ago received SMS: Fault ref ***0 has been closed. This is my second Hello Peter, no response. Now what?
