Wish complaint: Wish.com order runaround

I have been trying to buy my son an E bike. I found one on wish for a real good price. The order shipped and I waited for the delivery. I get a notification from USPS stating it was delivered. It wasn’t here. The delivery status says it was delivered to Grand Prairie Texas. I live in Illinois. I contacted Wish support. It’s an automated system only. No phone number or email. The automated system asked me how I wanted my money refunded. My choices were refund back to my credit card or refund via Wish cash. I didn’t want a refund. I wanted the product that I ordered, so I exited the automated system. I went back into the Wish support. They took it upon themselves to refund my money back to my credit card. I tried contacting them back again. They told me that the order has already been resolved. Their decision not mine! A few days later I found another E bike for $29. I thought it was to good to be true, an E bike for $29! I carefully scrolled through the entire listings details. Everything was completely legit. The listing even stated “package includes 1x electric bicycle”. So I ordered it on December 24th. I waited for it to be shipped. The order is still in fulfillment process. They extended the shipping date three times. Now it is January 9. I tried contacting customer support to find out what was taking so long. They said the product was sold out. They gave me a list of some BS items to choose from instead. I didn’t choose anything from their list.
