Business ProfileforComfort Suites

My company sends me around the country to do local auditing. These trips are expensed through the use of gift cards, **** or Mastercard gift cards. I have been exclusively staying at ************** which includes the Comfort Suites brand and have never had an issue with using gift cards. I have a valid driver's license and the gift card covers the entire cost of the room for the night. I have previously used this process for a Comfort Suites location in ************ and in **************. On Monday night I drove the 10 hours from ******** to ******. The desk clerk refused to accept the gift card. She did not call for a supervisor, nor did she care when I explained my traveling 10 hours and that I have used the same process in the past with ************** I called ************* and their supervisor didn't understand what a Mastercard Gift Card was. She also declined to assist me. This was an arbitrary decision by a desk clerk because I went to the hotel right next door (100 feet from this one) and they accepted the gift card. This was a Quality Inn, which is also a ************ brand! The clerk then left her desk and stood outside as I sat in my car frantically trying to make other arrangements. I am livid at the poor customer care service. Again, to be clear, if this is a ************ policy not to rent a room to someone with only a gift card then this has been violated 3 times in the last year. That is why I believe this was the result of a single clerk alone at night who did not want to investigate, and an outsourced customer service department that was ineffective. I want clarification on this policy and an explanation as to the contradiction i described, The ************* Customer Service Department, the ** **** of ******** Affairs and ** DA are next in my complaint chain.
