TFG "CUSTOMER SUPPORT" I HEAR YOU, I HEAR YOU BUT I WON'T HELP YOU!

On the 20th of November 2022 I purchased a pair of sneakers for my partners birthday on the Sportscene online store for their 40% Black Friday deal, the purchase went through I receive confirmation and the funds were deducted and I am expecting delivery. A week later I receive an email stating that my purchase has been cancelled and that there is no stock available which coincides with the last day of the sale. The next day I go into the store to querie the matter and miraculously there is an abundance of stock in the size I requested but only for 40% more than what I was supposed to get it for when on sale. I then contacted the online shopping customer support to establish what was happening with my order but all I was told is that the requested item is out of stock, I asked for the matter to be escalated as I could not understand how is it possible to cancel a order that was picked, sent to cart and paid for in full cancelled? A 2ic Rachmat then sent an email to say unfortunately they can not fulfil my order as they are now out of stock and supported the unfortunate with a R500 voucher, I emphasise the fact that I would have saved R1700 on the black Friday promotion I initially opted for. Rachmat eventually sent a voucher to the value of R1000 with an expiry date. I hurriedly search the online website for a item for my partner and upon delivery he found that the item was extremely uncomfortable. I took it back to Sportscene and was told that they will not be able to credit the voucher as it has already been redeemed and I will have to pay full price for the item I found suitable. I contacted Rachmat again and explained to her the reason why I purchased the item with the voucher as it would have expired should I have not used it. Rachmat then said she understood exactly what was going on and she would get back to me, after numerous attempts to get hold of Rachmat as she did not get back to me as promised all I was told is that unfortunately they are unable to assist and patronising me with "I hear you, I hear you" but unfortunately is it what is it, as I made it very clear that I initially would have saved R1700 then was offered a R500 voucher then a R1000 voucher and eventually got nothing after 3 months of battling with TFG "Customer Support "
