Starbucks - Unprofessional attitude and bad customer service

As a very Starbucks-loyal customer I must admit this might be the end of such loyalty and liking the Starbucks world. It doesn't happened to me but to my wife. My wife and I went this morning to Starbucks ROSEBANK after gym session. My wife been away for a while and she was looking forward to CALIM her BIRTHDAY REWARD (which will expire soon). I was waiting for her to get her free treat and move but she's been standing in front of Starbucks UNPROFESSIONAL worker who couldn't figure out how to claim her reward and then informed her that the system can't see any rewards for her? Even when a better trained person tried to help we have been told to leave our info (15 min from start) as they can give the treat for fee. I ended up paying for her choosen item (a small piece of cake) with big frustrating on my wife's face and on me as a loyal person. If the system is faulty then why we should be the victim. Wouldn't be a nice move if they give mt wife her BD treat and get info and sort out your technical challenge instead of her and me standing like ********* in the court room waiting for the judge decision! Absolute NON-PROFESSIONALIMS, poor training and lack of customer respect. Either bring back the great old team or do something about this team (Starbucks Sun 23 Sep morning team). We've left my wife's details (and I am sure your guys will neglected that as they didn't even show any sign of understanding or even suport).

Will see if I could attach her reward (screenshot) and I am expecting no less that APOLOGY AND REWARD TO BE RELOADRD WITH EXTENDED TIME.
