Part not delivered

Pathetic Service by Goldwagen and New Vaal Motors Bethlehem On the 09/11/2023 I went Goldwagen to buy a part and I was assisted by David, he took my Vin number and a picture of a part that that I wanted and he told me that they don't have a part, he told me that he will call one of his friend from New Vaal Motor Bethlehem (Ernest) and ask him if to check if they have this part, of which David confirmed with me that New Vaal Motor do have a part and I need to make a payment of R3226. 40, the part was delivered only on the 22/11/2023 only to find out that they sent incorrect part then it must be return and correct part must be order and I David advice me that there is difference that I need to pay of R1230. 00 and I paid that amount on the 22/11/2023. I haven't received a part till today and when I ask for my refund New Vaal Motors are refusing with my refund.
