Over the year, s I have recently spent alot of money here and hopefully continue too do so, but I have run into a problem with a microwave with a extended warranty threw CORNERSTONE. Tina is the person I, m dealing with and it is very frustrating.The repair people is threw Mcfadden Repair.The microwave quit at the end of October 2009. They came out too fix it and couldn, t repair with a control board, so the repair person said he had to take too his shop, and it would take a week, so after a week or so I called still not working he was going to try another part and call back in a week, so I called Tepperman, s to find out what is going on they said it is out of hand, s you have to call Cornestone so I called them again and talked to Tina who responded we are waiting to here from Mcfadden Repair and we will get back to you in aweek then I said the microwave only cost so much why are you wasting that much time on it she couldn, t respond all she could say was another week! Well here we are it, s Dec/26 /09 and still no microwave and you can just imagine what I think of Tepperman, s and the extended warranty threw Cornerstone and dealing with Tina, s lie.s. The last time I talked to her I would have the microwave back by Christmas, another lie I don, t know how she keep, s her job and as far as Tepperman, goes I will never go there again and when does a warranty place tell a repair person how to fix a microwave when he say, s it can, t be fixed.The only thing I can say is pay up you already have spent more than it is worth Now give me a microwave that Work, s.
