Selling stock that doesn’t exist and no updates on orders!

I ordered a fan on the 21st of June. I called to follow up to check on the status of delivery and was told they do not have stock and that it was expected to arrive within the same week. I was advised I would receive the fan on Friday the 27th of June or Monday the 30th of June. Nothing has arrived! I emailed to follow up and have received no further updates. How can you guys sell something that you don’t even have in the first place and then give the clients no updates regarding receiving stock? I thought they would be a reputable company seeing as they are associated with Payflex but that is definitely not the case. I will be reporting them to payflex as well, especially after seeing all these negative reviews about the company. I want my money back as I can see this fan will never arrive and it’s just a lie to **** people out of their hard earned money!!
