So frustrated with Telkom

I have alot to say ... I took out a contract with Telkom iphone 6 R499 ! 2 months after I got my phone we discovered another contract iphone 6 plus R 518 going off from telkom olso as debit order ! We did not take out that contract or sign for that contract! We have emails as proof and statement from police and everything ! We phoned telkom and the lady assured us we would get our money back (we have the names of the people giving us the contract also of the people names that we spoke with) and she will stop the contract and also the debit order ..for another 2 months the debit order went off , we had We to stop the order at the bank ! We have been trying ever since to get our money back but no one is helping us !! After countless phonecalls and emails no one is assisting us , we hear nothing back from telkom regarding this issue ... We lost almost R 4000,00 !
