TEVO / Bennett Read - Do not honour their Warranties

I bought a Bennett Read vacuum cleaner at Game. Bennett Read offers a one year Warranty. The motor broke after only 4 months. I took the vacuum to TEVO in Cape Town on the 18th of January (as per instruction from Game). Their technician inspected the vacuum and confirmed that it was a repair covered by the warranty. They said that it would take two to three weeks to fix, or would replace the vacuum if it could not be fixed. When I enquired after three weeks, they sent me a quote and said that the vacuum has not been repaired because I never accepted the quotation. I had the original job card, which stated that it was "Product under Warranty", as well as the Game invoice. They couldn't find either of these on their records. I spoke to someone this week and was told AGAIN that I had not accepted their quotation. Once again I was asked to email my proof of purchase and the job card (which I did). I have not heard from them since my last contact with them four days ago. They do not reply to emails at all, and also do not answer their phones.
