Incompetent Service and selling faulty products

We purchased 3 pellet fireplace from progress group at great expense. The MD Louis was quick to sell as a modern corner burner but failed to mention that they had not sold any of these before and his technicians were not competent to install it troubleshoot. It was commissioned two months ago and has never worked. Despite dozens of calls and mails, the MD response has been despicable with no solution on the cards. This has caused huge distress and given the chance they can give me my money back, take the pile of expensive rubbish away and make good on a new installation from a different suppliet at their cost. My advice is never to buy anything from them as they do not follow up, fail to meet meeting commitments and continue to promise that they will fix the problem when in fact they have no intention to spend the money to fly in the technicians who know how to install it. This is non-quality at the highest level and I would strongly advise people not to use this group.
