I purchased an air conditioner from Walmart.com which I received on June **, ****. Around August **, less than ** days after installing it, it stopped working. I called Walmart after having little luck with the company that made it. On that date I was told by a customer service rep that they would request a refund through the third party seller. They said if I did not hear back within ** hours to call back because Walmart would stand by me and return my money. **After not hearing back from them I called again on August **. This time I spoke to three different people, the last one named Dave. He told me my money would be returned in about a week. After waiting two weeks with no refund, I called back on September * and was told a whole new story. No, they can't refund the money and they insisted they had no record of me calling the second time. (Of course my phone has the record)
