I also was infuriated after recieving calls about prior surgeries and told them...not politely... to remove my number from the directory they were using. They keep using different numbers to call, also a heavy Indian accent which is almost impossible to understand.
Keep getting calls from this company U.S. Medical Association using different numbers where the calls are coming from. Callers are from India, states they are the legal U.S. Medical Association and they don't have any other numbers. Said I could call back to check and they are locate in CA. Told him all these calls are spam calls and that everyone who calls me states they are from U.S. Medical Association. Told him my numbers are on the do not call list, they are in violation of the FCC regulations and to delete my number and quit call it. Told him enough is enough and to stop calling me.
