Review Disappointment with the way these tec behave

Very bad sevices especially when it comes about repairing those techicien dont have manners to speak with customer making fun laughing of trying to be as if you own them...shame for company like courts for these kind of people...ive bought a heater i havn't been able to use for a day and when i send to chk the techicien say you dont know to installed and when you tell them to come for it to installed they make fun as if its is first time am using a heater...
