House & Home Diamond Pavillion Kimberley laptop complaint

Hi, I bought a laptop bundle at House and Home Diamond Pavillion in Kimberley last year June. Last week we busy moving things around in the house and the laptop was on the table and accidentally fell off and the screen and hinges broke. I went to House and & Home to find out if the laptop still has a guarantee and warranty on it. Alex Solomons, a sales guy, showed me in their computer that i bought it last year June so it should still be under warranty and guarantee. A lady with the name of Brumilda said they going to send it to the service provider HP in which she will phone me back to tell me what they said. The following day Camille phoned me to tell me that the people at HP says the laptop was broken intentionally and the warranty is void. I asked about House & Homes guarantee as the laptop is not even a year old so there should be a year guarantee on it and the Sales Manager said that they are just the middle man between the customer and service provider and that there is no guarantee on the laptop. I said that I'm going to phone head office which I did. I explained to that lady also what happened and she said that it sounds like customer negligence and that I should contact the Regional manager. She gave me his number,Rob Cubitt,and phoned immediately but he didn't answer. Hoping he will call back but nothing. I phoned numerous times but still nothing. Because the laptop is still under a year, I would like them to replace the laptop or refund my money. I would never experience something like this at another store. I would like a senior to please call me so that I can resolve this issue seeing that I can't get hold of the regional manager. Regards Joy
