Hello, the Walmart service center is very bad. I purchased a Windmill 12,000 BTU AC and installed it in our window. After installing it, we noticed there was a filter in the bottom of the box, there was nothing in the instructions on installing the filter, we googled how to do it and after removing the front cover of the AC, we noticed about 30% of the condenser fins were bent and damaged, I took pictures, this unit was clearly either used or refurbished, I called Walmart and they said I could only return the item or get a 10% discount, I was not happy with either option as we spent several hours installing the unit and I would never pay 90% of brand new price for a damaged used unit. The service rep understood and said they would escalate to see if they could get a more reasonable discount like closer to 40% as anyone would expect at least 40% for a used or refurbished unit, especially when the company tried to pass of a refurbished unit as brand new. He submitted the request and said I would hear back in 24 hours to 48 hours. 10 days later I had not heard anything, so I called back. To my surprise, the new service rep said the request had not been submitted, so I had to explain what happened again, and he understood and said he could only give me 10% discount or I could return the unit after spending hours installing it, at this point I was pretty frustrated, he could sense this and so he spoke to his "supervisor". He came back and said they could give me a 20% discount, not wanting to uninstall the unit, repack, ship it, and do it all over again when the new unit came, I unhappily agreed to the 20% discount, he said he would submit it and I would once again hear back in 24 to 48 hours. A few hours later I received an email that said they could not give me any discount and that I would have to return the unit. UNBELIEVABLE! they have some serious problems with their service department. They could have just given me the 20% discount, but now I have to return the unit, which weighs over 60 lbs, this is going to cost Walmart way more in shipping fees plus they will have to either scrap the unit or sell it as a refurbished unit unless they try to sell it as new again, which would not surprise me. In any case, this will cost Walmart way more money than to just give me a 20% discount, UNREAL!! whatever Walmart. You just earned an very unhappy customer, I will not be re-buying an A/C unit from you, I will get the replacement somewhere else! No regards, Dave
