Hôtels Homewood Suites by Hilton à Greece

I am a Diamond member via Hilton Honors. We booked a 3 night stay Friday thru Monday on points for first 2 nights and paid for the Sunday night. The hotel took the total cost of the three night divided it by 3 and charged me $223 USD for a Sunday night stay even though the hotel was completely empty. Upon check out I questioned the front desk and told them that if I had booked Friday and Saturday on points and then made another reservation for Sunday paying at the members rate, it would have been much cheaper. The attendant agreed, but couldn't figure out how to correct it and advised me to call Hilton Honors to resolve and she would make a not on file. I have called Hilton Honors several times and no one can seem to help and advised that someone would call me back, that was a few months ago. Today I called Hilton Honors and they said there was no case file, of course. Todays agent (Theresa) agreed that If i had booked as described I ”probably” would have got a better rate. I asked why you wouldn't just extend a diamond loyalty member the best price, she couldn't or wouldn't answer that. I asked for a supervisor to speak to and she advised there isnt any??? Really.... everyone has a supervisor at a call centre and I was willing to wait. Rude, unwilling to satisfy a loyalty member and a general ”it's your fault for booking that way” attitude didn't feel good either. Hilton2 Suites didn't care, Hilton Honors doesn't care about customer service and I will assume if any Hilton people read this they won't care. Sad ending to what was a good relationship for personal and business travel. I'm done with this hotel and Hilton overall. They have the absolute worst customer service and there are plenty of other choices of hotel chains offering better loyalty programs and I bet they call back their customers to resolve issues. If you stay at this hotel and have a billing issue, GOOD LUCK
