bad service

PRO FORMA INVOICE : INV0011-7994 25/11/2024 Round about the 25th of November 2024 I bough a Telefunken 1.5L Stainless Steel Blender and a few other goods from the Auction. On arrival to collect my goods we've been told my blender has been given to one of the Bulk buyers, I told the lady sorry that is not acceptable, that was an Item that I bought and paid for I want it, very rude I was told no you can take another blender that they had a lot of in stock, I asked the lady so why didnt you gave one of this plenty in stock blenders to the bulk buyers, she rep**** because the buyer wanted the stainless steel one. I took the blender she gave me and asked to speak to a supervisor or manager, again sorry mam he is not available you can phone the office. So I left. At home I opened the blender that was given to me, the plastic shavings was lying in the box, switched the blender on, hell of a noise and shavings spinning out the blender. So I phoned the office asked for a number or to speak to a manager. A number was given to me of Mr Helder De Al****a. I phoned him and explained the situation, he told me that was wrong from the Auctioneers to gave me another blender, but I must come in the next week to get another blender that is working. So the following week we went to Auction Operation to collect another blender. Sorry mam we do not have, we only have the Plastic ones and we don't want to give it to you we want to give a proper one, I said fine but when, oh in 2 weeks time. 2 weeks later my son was working in the area and he stopped to collect a blender. Still NO blender. He was told no in January I will get a new blender and that Helder will arrange with one of his staff that stays in Vereeniging to drop it at my house because we already travelled to them 3x with no luck. On Friday the 21st of January 2025 my son phoned Mr Helder to find out what is happening. The auction they had there was a Russel Hobbs blender, can we get that one with maybe one of the hand blenders the value will be the same at the end. Helder told my son in a very rude manner, sorry they are not allowed to do so, we must wait until they have stock of the exact make of blender that I purchased. BUT THE DAY WE COLLECTED I WAS GIVEN ANOTHER MAKE BLENDER- IT WAS NOT A PROBLEM WHY NOW IT IS A PROBLEM TO GIVE ANOTHER MAKE???????????? So my son told him please just refund us, we loosing money because we live 60km from and 60km to Auction operation, 120km trip a time and we were there 3 times without any luck. all our phone calls, he told my son he will walk to the ladies now to do my refund. Still no refund!!!! SO NOW I DO NOT WANT A REFUND......PLEASE DELIVER A BLENDER TO ME FROM THE SAME VALUE!!!!!!!!!!! I buy from the auction a lot and this is the first time I had service like this.
