Poor management

I just need to share my dissatisfaction, being a tea ***** and not feeling well, I opted for a tea instead of cold drinks or alcohol. It was just an office lunch to round off the year. I ordered and was served a pot of tea for one except the teabag had nothing to steep on, I called the waiter to show him that it was literally hot water and asked if they can bring me another teabag. To my surprise on payment I was charged for 2 teas, I called the manager directly for him to resolve the matter, instead he was adamant that they charge when 1 pot gets a 2nd teabag. Does it mean I had to drink hot water and milk and get charged for no tea? Manager on duty this afternoon was just nonchalant and never sent the waitress to apologize for the non communication of their rules. Fireroom no more, and failed me on a lousy pot of poor tea, although the menu is fairly pricey, but i didn't mind the support.
