Ninja Crispi and Ubuy

I purchased a Ninja Crispi air fryer from Ubuy, It came from the US, but they did not advise me that the product works on 110v, not 220v. When it arrived I immediately contacted Ubuy, and after a bit of to and frow, they agreed I could return the product, It was all set for collection by DHL, and Ubuy retracted the collection at the last minute for no reason at all. I asked why and was told that on their website they say the product may need a converter. Therefore they could not accept my return. as far as I know, it's normal business practice to be able to return something if you don't want it, for any reason, but not Ubuy! As a warning, check with the supplier before putting out the money, that the product will work in SA. Secondly, be wary of Ubuy. I certainly will not buy from them again
