Walmart review: online grocery delivery - unjustifiable flagging accounts

My Walmart online grocery account with Fishers, IN was flagged because of reporting too many honest facts about their flawed grocery delivery service and because I used too many promo codes. Apparently, they don't want you to be honest about their continual issues of out of stock items. They send you a survey and if you give them a low rating too often they don't want your business anymore. The flagging is determined by the grocery manager's discretion in an effort to prohibit you from ordering in the risk that the department will receive another bad review or customer service call. Instead of raising their standards to improve service they simple ban you as a customer. I placed 15 or more phone calls including speaking with corporate and the only resolve was to open up a new account with a different email address. I received no apologies and most of the people I spoke via customer service, call centers, consumer dept. and even corporate acted as if their hands were tied. Many were downright rude!
