PAyment deducted - No Goods received - Follow up is Terrible

Please Help - Terrible service from Zasttra - I purchased a tablet cover and glass protection for my tablet on the 17th August 2017 from ZAsstra.com. Until today I received nothing although the money has been deducted off my account and following up has been a nightmare. I purchased my order and paid via Zapper. After some time I thought there was a slip up so I reordered the same 2 items on the 8th September. Again the transaction went through Zapper. Zapper send me a confirmation of both payments as well as confirming that they spoke to Ashley at Zasstra about my order. Both times the money was deducted off my account although now Zasstra says they can’t trace any order from me. I again spoke to Zapper and a gentleman there by the name of Sanele (Service Desk Consultant/Coordinator – Zapper South Africa) was very helpful. He send me a proof that both payments went through plus he cc'd me in a mail that he sent to Ashley at Zasstra about my query. I have phoned Zasstra 4 times already and I'm just informed that Ashley is in management and doesn't speak to the public. I have sent Zasstra 3 mails with proof of payment already but no response. They point blank refuse to speak to me although R 1267.96 is off my account. I find this shocking and the fact that they just ignore me makes it worse. I NEED ANSWERS and Sanele from Zapper is doing his part but Zasstra is just ignoring me totally. Since when does a company's management not speak to someone from the public? are they too important? A company like this DONT need business from the public !!! GET BACK TO me ZAsstra - Pay back my money for the one transaction and send me my goods for the order placed –It’s been 3 weeks since my mail and you don't even bother to answer me . TOTALLY Pathetic!!!!!!
