I recently had a very bad experience before, during and now after a week long stay at a Marriott. I have never been so enraged over a problem with a hotel, certainly a Marriott where I usually have such high regard. All I want to do is speak to someone in Marriott’s management to discuss these issues and find out why they happened. I called Marriott customer service and was supposed to get a return call within 7-10 days. It's now been over a month with no call back. Emails to Marriott referencing the call contact # have for the most part been ignored. During my stay I requested to meet with the GM several times who never even contacted me. Has Marriott customer service changed? They used to be so good at responding to problems. I have always got the courtesy of a reply.
Any suggestions?

Thank you.
