Carelessness

I bought a Hisense TV from Hi-fi corp, and the device stopped working less than three weeks after I bought and I went to the store to complain, sent a technician who just came in I don't know what he did because I wasn't home that time and the device worked for less than three days and stopped, because I am working did not get a chance to make a follow up immediately but I went there to report it again and still it did not work. The fourth time they came I refused to let them open the TV because why after so many times do you want to open it, then the sixth time I let them open it and I am talking after a year and then the technician said to me and my family that it cannot work because of ****roaches after a year of not working what did they expect it's just standing not being used and the funny is he gave a report that the device had physical damage which he did not tell us and secondly he is the only person who has ever took that device from the wall were it is mounted and if he says there is physical damage the he is responsible, but then Hisense goes on this ****'s word against the customers word they have not even sent someone else to check if the report is true, that says to me Hisense does not care about their brand, it says to that hi-fi corp sels damaged goods and they don't care
