I also keep getting calls from this number about a vaccine study. They finally called so many times I answered and asked them to take me off their list. She said there was no list but if I just answered some questions that "maybe" it would stop them calling. I told her I was not interested and to STOP CALLING ME. They call every single day, sometimes more than once. I hope it stops soon.
Just got ANOTHER one! They have changed their caller Id. It now just comes in from San Diego and the number. I'm also on the no call list! I have filed two complaints. Here in Colorado it's five hundred dollars the first time and a thousand the second. I think. It's something like that. But I have my computer to record any call on that line. I will get my money from them. Mostly because They are so rude and won't stop. A class action lawsuit sounds good to me.
Received 2 calls from same number yesterday and today, could only hear someone breathing on the answering machine, no other back ground noice! My phone number is also unlisted.
858-401-7263: Answered and some foreigner started babbling something I couldn't understand. I spoke very loudly over them and told them do not ever call this number again! Will see if that works.
