Caller: Sangreta

Selling advertising in doctors surgeries. Most likely just a scam. Understanding English was obviously optional.

Claim that you've won money. but they need your credit card number?????

4 phone calls Today alone, they let it ring maybe twice, then hang up.

They don't stop calling! I've worked in Advertising and Marketing for over 30 years. Any Marketing Manager spending corporate dollars this way is quite sad. As is the Brand that is OK with being associated with harassment.

They call to offer 80% holida package.
it's spam
