Mr. appliance

The refrigerator in the garage was not cooling and ice was building in the freezer wall. The thermostat and defrost heater were replaced but when it came time to plug the refrigerator into the outlet that had been on for the last 17 years, it shorted. The technician used an extension cord to get power to it from a hallway outlet inside the house so he could test the parts. He told me that the GFI unit in the garage was bad and needed to be replaced and once that happened, the refrigerator would work. I hired an electrician to replace such GFI but he assured me that it was in working order. After I explained how this issue had come up, he tested the refrigerator to check if he could give it power without having it connected to the distribution box, which sends the power to the different components in the refrigerator. The refrigerator turned on without shorting, but once connected to the distribution box it did. I called Mr. Appliance and asked to talk to a manager. Mark called me back and I explained the situation. He asked me to give him time to investigate and that he would come to check the refrigerator if needed. That conversation took place on January 29, 2020. Since then, I've left messages on Mark's phone on February 12th and 26th. No response. I called the shop on February 19th and 26th asking to speak to a manager. Message is taken. No response. I am looking for a refund for the service I paid, since I have been more than patient on this issue and it's clear I am getting the run-around from this company but I cannot talk to anyone ! Please help

Mark was a gentleman and knowledgeable and he fix the microwave. I would call on him again, again. he put on his little orange booties before coming in the house that meant a lot to me. Thank you again Mark
