Bad after service from SAMSUNG online store

After sales support service is absolutely pathetic. I bought a very pricey Samsung machine and wanted it returned as that was clear on the invoice and receipt that they accept free returns. Well, It took 5 days for them to deliver, that is 2 weeks ago. When I opened the box i realised it is not a washing machine but a dryer, which was my mistake. I phoned Samsung and whatsupped them on 8 March 2024, explaining the mistake. They accepted and asked that I send photos- that was accepted by Steven in the support team. He confirmed telephonically that I would have my money back in 14 days and the courier company would collect the item. Well this is almost 7 days later and no one has attempted to let me know what is the progress on processing my refund and collection of machine. It is truly unacceptable. I even offered to bring the machine back myself in order to get my refund. Now that I read all the bad reviews I want to urge all consumers to rather buy from Tafelberg of a reputable shop where they can deal with your problems immediately . I even could here that Steven was taking my call from where he was working, at home as I could hear dogs barking. No wonder there is no service ….
