Humiliated by your General Manager!!!

I was humiliated by your General Manager, this morning during check out, in front of other patrons and staff. When I checked in yesterday, the lady who checked me in told me that I had R200 towards dinner. I asked her twice what the amount was and she confirmed it twice and even wrote it on the slip as proof. Today when I checked out I was told I needed to pay it back because they had made a mistake.<br> <br> Your GM then asked for my boss' number which I gave to him because I had nothing to hide. I asked your GM to call the lady who checked me in but I was told that she is off duty so he won't call her. Instead he called and spoke to my boss. I am still very new in my job so you can just imagine the impression my boss got of me, as she still doesn't know me well.<br> <br> My stay was pleasant, except for how I was handled by your GM this morning. Please take him to a refresher course on customer service. He also needs to learn to gather facts first and interrogate them before making assumptions. He doesn't know me from a bar of soap, so why would he just assume that I am trying to deceive him? Why would I jeopardise my new job and my children's livelihood over R200?
