pathetic service

I paid an amount of R400.00 on Sunday that brought the account up to date. The balance is only due at the end of this month. A restriction went onto the line on Monday morning. When I called to have it removed I was told to wait 2 hours and that the R400.00 I paid is reflecting on the acc. There are 2 numbers on the acc but only 1 line was opened. I waited a bit longer and then called again for this number and was told again it will take up to 2 hours. After switching on and off numerous times I called back late yesterday afternoon. I was told that it will be unblocked immediately. He guaranteed it. But still nothing. The call centre is closed after 5. I have a toddler and an elderly person living at home. What was I supposed to do in an emergency? Now I must wait till 8 am to try and get this sorted. But what's the chances they'll get it right this time.
