I never solicited a call from this number. I have followed instructions to stop it; they are ignored. I would like to invoice them for my time in listening to unwanted calls.

Any further information available?

They called again. Got this number blocked on my cell. It just shows as, a missed call blocked.
Don't answer this number. Its a scam.

SOS something... also subscriber service, I 'apparently' won 2500 'travel-dollars' for a vacation in puerto vallarta mexico, through a call we supposedly did to a retail store... I never do that, i go in person if i need stuff from a retail store.
Then, how do those travel-dollars translate to 'real' dollars...

The message didn't start until after 3-4 seconds of silence.
