I have purchased a hoover machine from game awhile back and now having trouble with the machine, i was told by my mum to send it into game for repairs as she has done the same and game informed her they will send it to hoover supplier for a quote for repairing... so i had done that and the lady tells me that they can send it in for a quote but if the quote comes to R700 and i refuse it that they will charge me a rejection fee!! And I ask how much will the rejection fee cost and they said they have no idea it can be any amount which i find ridiculous!! My mum had not been told anything about a rejection fee. They took her machine in with no trouble and yet in being hassled and told the repairs might cost a lot so it's better i buy a new machine at R600.. let me mention that my mum had no proof of purchase and neither did I as i am aware my guarantee is over
