Scam or pure negligence?

Besides the worst Customer Service ever, this company overcharges most of the wines and uses coupons as fishing bait to allure customer and divert our attention away from their high prices. What makes this seller awful it's the negligence, discrimination and mistreatment you get from most of the customer service agents. It feels like they are trained to treat you like worthless consumer. After I complained about issues with my others during their "fictitious" system upgrade, they decided to block my account without notice or any explanation why. Some of my orders were charged in full, but delivered with missing wines. My credit card was charged three times for "orders" that were never delivered. The issues were never clarified or resolved, forcing me to open disputes with my credit card. I have opened a new account after that and once they found out, the new account was also blocked from the blue. At the end of three months of complaints, no responses and 5 blocked accounts, I filed a complaint with Better Business Bureau (BBB). So, BBB contacted wine.com twice and no response was sent. BBB then advised me to write as letter to the Attorney general, which I am working on right now. Wine.com must improve its customer service practice and policy if they want to stay in the Market.
