I had a stay in January 2015 at Marriott, Lima, Peru. We had some minor issues that I sent an email to the front desk manager. I got a canned reply back from them, acknowledging problems and offering to 'deposit' Marriott reward points and requesting to come back and a promise of good service and a room upgrade. Well, as a gold I usually get an upgrade at this hotel but I appreciated the gesture.
Since then I have sent 4 emails asking about the points deposit and suite upgrade confirmation on my next stay. It went to a specific person's email box as they are the ones who sent me the offer.
To my surprise, that person with Marriott has not bothered to respond to any of my emails. I am wondering now if this is some kind of joke being played by Marriott - Lima.
I am hoping some one can shed some light on this matter or may be someone from Marriott Customer Service will see this message and encourage Marriott, Lima to at least acknowledge my emails and respond.
Why make offers when you do not plan to keep your word?

I would email Marriott Cust Service through Marriott.com and provide the correspondance you received from the hotel. My bet is that it will be fixed fast.
