WORST SERVICE EVER FROM THE MIDRAND BRANCH

We bought on 02 June 2023 2x graphics cards online from Rectron Midrand for a customer. The cards have 3x output ports as the customer needed to connect 3x monitors to the PCs. When we opened the 1st card's package, we immediately noticed that the card requires a 6+2 (8) pin connectors which the PCs don't support. Tis was nowhere stated on their website. When we tried to return the cards, the one card was credited but they refused to credit the opened package card. The product manager was unavailable at the time to make a decision on the matter. The next day, we contacted our account manager who followed up with the product manager. He refused to have the card credited as the package was opened. We have met their required t's & c's yet he refused !! According to their terms & conditions, the card was in the original package, un-used. NO damage at all to any of the packaging, outer nor inner. I forwarded the credit note to our account manager on the 8th of June requesting his assistance with the refund. I was informed that al refunds are processed on Thursdays. No refund was processed on either the 8th or the 15th of June. How log do they take to do a refund ??? !!!! WORST SERVICE EVER FROM THIS BRANCH !!!
