Update. Called the front desk again. Apparently, after looking into this further, they discovered that my TA booked me in with other people on a convention, and thus was not entitled to the housekeeping discount. HOWEVER.....I am NOT here with a convention or group....and finally got the money credited to my account. For those of you who said I shouldn't worry about it or whatever, here's the deal. If I am entitled to the money for giving up housekeeping ,then I am entitled to it. Simple as that.
