Their Agent makes a mistake and I'm penalised

I've been out of the country and as I've always paid my account cash, the service was disconnected. Upon my return I phoned DSTV and requested that I pay via Debit Order. The debit order detail is provided and the total amount payable the 28th of June is confirmed. <br> <br> My service is reconnected on the 23rd of June.<br> <br> The 25th of June my account is disconnected and upon investigation, it is because the agent I spoke to never update the payment method to debit order.<br> <br> My service can't be reinstated now until payment which is on the 28th of June.<br> <br> I have no words for how appalled I am by this!<br>
