I bought a smart TV and took out the extended guarentee. Having had my smart TV go in for the same repair three times without the problem being resolved I was told on phoning Knowhow that as it was 14 days since the last instance of it being taken in and not resolved I could request a replacement. I took the TV into store and waited for them to contact me about my replacement. Three times now I have had to phone and once I got the store to phone about progress on the repair/replacement and each time I was fobbed off with it being looked at, being on the bench etc. Now under the agreement I have not had a working set for twenty one days and it shows at this present time every indication that it will be another twenty one days. This is without taking into consideration that the set has been faulty with the intermittent wifi dongle removed now for months.I posted this story on Trust Pilot and had a response that they would look into it, but clearly they are not doing so. I do believe that this is the worst service I have ever had from a company, but it seems that there is little I can do about it. Avoid them if you have any alternative and don't believe a word they tell you
