Lines disconnected while proof of payment has been sent

My business line has been suspended even though I have made payment. I have sent the payment through on 3 occasions now and called 3 times as well only to be told that I have to wait for the admin team to allocate the payment and that the accounts department cannot assist me. It has been 3 days of no telephone or data service since the lines were locked and no answers as to when the "payment will be allocated"
