Multichoice incompetence!

On the 20th of May my father paid for our Dstv subscription via online. He followed all the necessary steps. Even got an sms notification informing him that the money was deducted from his account. Yesterday morning when we turned on the tv we found out that the account has been suspended. We called the Dstv Call Centre for assistance, to our surprise they say the account has been suspended because they haven't received any payment. We insisted that we have paid and we even had proof, we sent the proof of payment to them vial e-mail and they said everything will be resolved in an hour tops. That was yesterday. It's getting close to 24 hours now and the account is still suspended . This is frustrating really. The whole of yesterday we were calling and calling the help centre for help but still nothing has been done. Such incompetence cannot be accepted. Really disappointing.
