Refusal to replace/refund faulty Hoover Vacuum Cleaner

<p>I purchased a Hoover Power 5 Pet Vacuum cleaner, specially for pets with a large capacity, etc.</p> <p>Ever since I bought it it kept on overheating and cutting out after literally vacuuming for 4-5 minutes. the filters were clean, there was hardly anything in machine as I hardly had a chance to use it properly. I took it to Pick 'n Pay and was told they have to send it away. I got it back and after testing it with a timer and it cutting out again after 2minutes and 33 secodes I once again returned it. I was once again told you have to send it away for repairs twice before they refund/credit/or give a new machine. (this does not make sence as I paid for a NEW machine and now I have a faulty second hand one) Any case I just got the machine back after the second repair. First time it cut out at 6minutes, then you have to let it cool for more than an hour and it cut out at 5 minutes. I am super unhappy and Pick 'n Pay does not get back to emails. It is also impossible to get hold of Hoover in South Africa to complain to them directly. This is the worst purchase ever and I want my money back as the supplier does not want to assist the client.</p>
