Outgoing calls barred

I have just been overseas and used the ROAMON / ROMOFF facility. I received an sms saying it had been successfully de activated<br> <br> I cannot make outgoing calls and have spent an hour and a half of my precious work time at the Fourways Mall store. At first they couldn't get through to the Call Centre. After all that time I am eventually told it will take 24 to 48 hours to fix this problem. This is not acceptable. I am paying for a service and I need to make work calls.
