JVC Smart within Warranty

Despite numerous calls (6 in total) and two e-mails, my JVC Smart TV which I purchased via Groupon in April last year is still standing in my passage and is not working. It was not a cheap purchase through Groupon and I am now regretting making this through them! The TV flashed whilst we were watching it 3 weeks ago and will not reboot. Despite my too many calls to Groupon and two mails, I have not had any feedback as to the progress or the outcome of their intention to have same repaired! The TV is still within the warranty period and this will expire next month. I have made many purchased via Take-a-Lot and expected Goupon's service to match theirs. I am am extremely disappointed that this is not the case. I just want the TV repaired. Given the cost, this should be a priority for them. Not an acceptable level of service by a long shot! I will not be making any further purchases from them, that is a given! I intend to hand this matter over to the consumer council should I not hear from them within the next week! I caution anyone planning to purchase expensive electronic goods from them to first consider alternative options!
