Amazon poor service

I bought a Canon R50 camera with a lens from them only to receive the wrong order (just the body without the lens) Phoned customer service on the first day the agend offered me a 20% refund for the missing lens or a re order with the instruction that the new camera would be send out to me and I just then need to send back the old one. I opted for the re order as the 20% would not cover the cost of the lens. At the second day after hearing nothing from them I phoned client service again , this time the operator rold me there is no mare stock and the best they could do is a 10% refund on the missing lens. I needed the camera urgently as my daughter is starting a course where she will need the camera . Amazon had the lens seperately on their website for 4k but they would not offer me more than 19% this would mean that ai would have to pay in to correct their mistake. I appreciate the second agent trying his best but his manager would not budge. I am returning the order hoping that I would get my full refund but I would most likely never buy from them again.. J ***
