Don’t buy after care plan

I bought V8 animal dyson hoover from Currys with after care plan of 5yeras at an additional cost of £60. After 3years I have a problem with the machine and it has stopped working. I went and gave the machine to Currys in Reading. They didn’t repair it saying it is damaged. So I had a crack on the plastic body on the first year itself as the body is made of plastic. But hoover always worked fine. Now they give a reason that it has cosmetic damage and they cannot repair my machine. But I have never asked for a new one. I’m just asking them to fix my existing one! I called customer service wasted 26mins on phone and was passing the parcel. So basically they will find a reason to not fix your products. Please be aware before paying extra for after care plan.
