Poor Service

I purchased a TV set 50inch Sinotec UHD with a 5 year warranty at the store Shop 34 Fleurdale Shopping Centre in Bloemfontein . I only had the item since the 22/08/2020 , in which this TV set had a yellow line on the one side . When I took the TV unit to the store on inspection on 25th of February 2021 the unit gave in and stopped working during testing . The store Rep : Bongani who assisted us re assured after the 21 days assesment from Sinotec my request will be granted. This was my second TV unit I purchased from the same store also during last year the 18/08/20 , of which I returned immediatly within a few days of which I paid in extra to purchase the Sinotec Tv unit which also had technical problems. There for I informed Bongani that there will be no replacement but I would like a refund I am not a happy client because of the poor quality of their items . The Rep Bongani assured us that after the assesment I will refunded in full . I recieved a call from the store Rep Bongani informing me to come instore ( 17/03/21) so that a Refund claim form had to be completed with a copy of my banking details reason is that the amount was above R3000.00 , therefor authorisation must be given within 7 days guaranteed for a refund from Head Offïce . The Rep informed us that everything was sorted his informed us the store Manager was up to speed with the claim. Seven days elapsed today , I went to the store , Bongani the Rep was unavailable and no else knew anything they just shrugged. their shoulders aswell the Supervisor and store Manager , all I was getting was excuses and not a straight answer for their incompetence. I am really irrate , a refund no later then Friday this is huge inconvience . Mrs LAY de Koker ***
