DSTV is charging for services that was not rendered

To whom it may concern, We requested a change of ownership to be done and a decoder transferred from my Father in laws account to my wife’s account, the change of ownership was done and the service was activated without my knowledge as I was supposed to pay my premium up front as well as the activation fee, I wanted to reactivate my service and realise there is an amount of R369.00 outstanding, my decoder was disconnected and I was unaware that the services was activated. I requested my husband and father to contact DSTV to inquire about this, he was sent from pillar to post and agents promise on numerous occasions that they will contact him back or drop him a mail, no feedback was received and we are still waiting, we were provided with reference numbers but is was un frontally misplaced. I would like your assistance to investigate this matter and provide feedback as soon as possible otherwise I will have no option and option professional advice.
