Testing debit order

I bought a phone on contract in Nov 2018 through the phone. On 13 Nov 2018 before I even received my phone R499 was debited from my account. I phoned and asked why did they debit before delivering the phone and why debit on 13th while i selected the 15th, this was very inconveniencing it was two days before my pay day and i was left broke, then I was told the debit order is for testing my account. On 15 Dec R988.18 was debited - this was my monthly of R500 plus other activation and sim charge that i paid once off. I then phoned to check when do i start to count for the 24 months contract and i was told from Dec 2018, then i asked what about the R499 testing fee that was debited, then i was told it will be refunded in January 2019 or February 2019. Feb 2019 passed and no refund was made. On 13 June 2019 i phone again to follow up on the refund and i talked for a long time with Mr. Lindani Nxumalo, *** who instructed me to email him proof of those first two debit order and i did. He promised to resolve the matter but the useless Telkom worker did nothing about my matter. Lindani Nxumalo did not even bother to phone me for feedback. I have not receive my refund and no one seem to care to resolve the matter. Well am sick and tired of Telkom nonsense. My contract supposed to end in Dec 2020 but then since no one care to resolve the testing account **** i will make sure not debit order goes through from Nov 2010, i will end my contract a month earlier because you idiots think you are clever.
