JEDENZED: I'll give the manager I emailed due time to respond to my message before going down the road of a public shaming on FB, if even then. I'm not completely sure if I have a valid argument but I feel my case is legitimate. I hope they will take the opportunity to do right by me and welcome my spend rather than leave me aggrieved and unwilling to ever shop there again...
It all comes down to how well the company handles the error, and treats you IMO, as to how you respond.
