Line disconnected but account up to date.

im a new client with Telkom since end march.... i paid the accput via debit order end of april r781. At the end of May the accoount was paid again the monthly instalment which is r350 via debit order. the line was disconnected in May without even receiving a call from them but i paid. when i went to the branch im told the first debit order reflected late on their side so i must wait for end of June for my line to be reconnected. Its so inconviniencing that im treated this way whereas i paid my account now i must suffer because of their problem im so disappointed int them a lot
