Unable to claim on my TV Warranty

@PicknPay Hyper William Moffat

Okay so I purchased a Sinotec 55" UHD TV in 2018, with a 5 year warranty, TV is now faulty and the store where I bought it, says they're unable to reprint my till slip as "the system doesn't allow them to go that far back" . The gentleman who helped me, tried his best to assist and escalated it to their H/O for further assistance. Its now been 4 days still no response. I'm so disappointed in Pick n Pay as I was under the impression that they had the best after sales service of all the retailers, which is why preferred to go to them. This is totally unacceptable, if you sell products with 5 year warranties, then you should have access to those invoices..
