iirc under the sale of goods act,you have 28 days to list all faults and report them to the suppling dealer and ask them to rectify,they will no doubt try to get you to claim on the warranty(if 1 was issued)up to you if you want or refuse and say to them that they have to fix it,ie its not fit for purpose,and if theyve got any brains when you say to them you have seeked legal advice watch them buckle. phone up the relative peeps for advice they are very helpful.
