This is the third time I have received a call for the same thing - medical procedures / surgery / drugs during pregnancy - looking for potential lawsuit customers. Sounds like the calls are from india. Last time the phone number came across as "restricted". Each time have asked to be removed from the call list and advised that we are on the do not call list. But the called is persistent/demanding and says "just one more question" before I hang up. Company is something like "Health Safety" - real generic. Hard to understand due to the accent of the caller.
