Worst Product and Customer Service I Have Ever Experienced

I got this product a couple of years ago when it was etsypro and stayed with them despite the site being down most of the time. This is the only one out there and it’s a shame because who ever is running this app is not professional enough to deal with other businesses. My business suffered quite a bit due to the fact that the stores were down the entire holiday season. They offered the upgrade and like a dope, I believed it would make things better and it made things worse. I have two etsy stores and all of the sudden I couldn’t display both. When I contacted them they said I would have to buy another cart at $50 so they could help me. I said I have been a loyal customer for years and that their terms and conditions state that the license is per website, not per shop. It was the last straw, their product is problematic, slows the site down and now they want more money. I asked for a refund since I never used the cart due to the malfunction for the two weeks that I had it on my site. They refused and closed the case. I opened another case asking “Please give me my refund.” They closed my account, so now I can’t even communicate with them. They gave themselves a positive review here, that should be a clear sign that the product sucks. Just don’t do it, and definitely don’t give them any money.
