Don's Liquors & Wine review for SC Back in Stock Notify Me

Been paying $5 a month for years only to figure out that they have sent 0, yes ZERO, messages all of these years. 6,000+ messages have been pending. I expect them to reach out to me in this case and explain there is an issue instead of me having to figure out that thier app is not working. I am sure they will claim that I didn't do setup correctly or didn't do some action but why take my money all of these years and do nothing to help me?
