Same here, just got the call but didn't answer. No message, and I'm expecting repeated illegal calls going forward. I'm on the no-call list, so unless they've found a loophole they are in violation.
I've been getting that call for several months. I guess if I stayed at a Hilton, I am on that list. I followed the advise from db. I called the number and selected option 2. A live person answered and I asked to be removed. They simply asked for the number to be removed. I did not have to give them my name.
I did as instructed by db and MT2237 above. Spoke to a Leila and requested to have my # removed. Advised he that I was on the National Do Not Call Registry and advised that if I receive another call I will report the company.
i also called the number, pressed "2", spoke to someone who asked for my phone number, and was told I would be removed from their call list. we shall see.
