General Electric Appliance Part returned and will not respond or refund money Nationwide

I bought 2 parts from them to repair my stove, the first never arrived, I disputed the charge and they rebilled my credit card.  The second did make it but did not work, it was returned almost 3 months ago and they will not respond to questions about the return, I cannot get through on the phone without hours long wait time and 4 emails went unanswered.  I disputed the charge an they recharged me again.  We contacted the store we bought the stove from and they tried to get help from thier contact.  They told us they could not do anything.  I now have an open case with the BBB in Kentucky to try and get some response from GE, they have charged me $272.11 twice and will not give me a cent back, or respond to me messages. I would never buy a part from them again and will not be purchasing any GE appliances again.  I should have gone with my gut and bought the LG.
