Guests were not provided receipts for their corporate stay. I have since submitted 3 different requests and have received a run-around each time. First being told that the guests themselves must request a receipt and that I cannot request it to be sent to their address on file. Not even my email, THEIRS! That they themselves must call and leave a message for someone to eventually get around to sending it directly to them. Second, a completed the online receipt request form on their website. A week later and still radio silence. Third, I tried to call again and see if I could speak to someone else and request the receipt to be sent directly to my managers whose names are on file for each of the rooms. I was transferred to the accounting department, the voice message tells you to press zero if you would like to request a receipt. Someone answers tell me that I actually need to leave a message to request a receipt and they direct me to a voicemail box where they tell me to leave a message for anything other than requesting a receipt and someone will get back to me within a couple business days. I am not even trying to get them to send it to me. Just to the person on the account. I was the one who even made the reservations. What does a girl have to do to get some help?!
Such terrible customer service, I am in awe. Terrible experience.
