Account double charged

We made the mistake of buying a DSTV explorer. I installed it myself and called the call centre to have the new smartcard activated. After the disconnection of our old card and the activation of the new we realised that we did not have a smartlnb. I requested the lady to deactivate the explora for mow and reactivate the old one till we get the lnb. She told me she did. We went to the dstv here in toti and was told that we are in arrears (yet our debit went off). a week later my dstv was disconnected and i spent an hour on the phone getting it sorted out as the lady never disconnected the expola and we were debited for 2. I was told that they would sort it out. Since then we have done 2 more debits at R1143 instead of R780. I want my double debits reversed and I want to be credited for the 3 hours I spent on phone bills. I spent 2 more hours on 2 different calls as I was disconnected for non payment twice again. If this is not done I will take my complaint to a ombudsman! DSTV - your service is **** and I hope Netflix makes millions in SA.
