Poor service and no refund

During January 2024 I ordered 2 twin and 2 single soap dispensers, & garden lights. The soap dispensers had to be returned to take a lot because they were scratched & damaged. Besides, the complete unit was advertised as "stainless steel" but that was not true. The bottom part was plastic. After returning BOTH single& twin dispensers, I was refunded for the twin disensers (R798) but only for one single soap dispenser. (R229). This, despite giving proof via email from Take a lot itself, that BOTH single dispensers were returned on 29 January 2024. So the refund for the other single dispenser remains outstanding. I am now owed R229 by Take a lot. However, Ms Trisha R , who is the customer service agent, refuses to refund me, although I forwarded her the proof. She initially asked for the original order. Which was given to her. Then she asked for the proof of return , which shows BOTH single dispensers returned. After receiving all this, Ms Trisha R informs me that the matter will have to be escalated. But no refund of the outstanding R229 has been received. Furthermore, the return tracking page on the take a lot app still shows that I must return the item, whereas BOTH items were returned on the 29 Jan 2024. So basically Take a lot has the items plus my money. One refund is still outstanding . Please could you intervene on my behalf. Regards Fawzia
