Worst service EVER

My dad was called by a pricelock agent and he signed up for pricelock black friday deal. The explorer was delivered on Saturday 7th December, thaat every day the installers came and advised that it cannot be connected the way he wanted and as was advised to him mby the pricelcok agent that everything would remain the same, the current supscription will be cancelled and it'll just be the pricelock with extra view as he currently has. However this was false information. Monday 9th December my dad called the contact centre and sms'd pricelock, he got an automated response that they would contact him within 72hours, Tuesday 10th december he physically went to the N1 city walk in branch to enquire about this, they then advised that pricelock is a separate division and that they can only email them to collect the decoder since he now wants to cancel it and they would call him.Nobody called or collected.. Meanwhile on calling Dstv on 12th and 13th December they advised that he now has 2 accounts, etc again this was not explained to him, again they said that they will email pricelock and they will call him. Today is the 18th - NOBODY HAS CALLED or collected the decoder yet. How does he get hold of Pricelock division because clearly they are like typical telesales agents that sell and then their job is done.
