Caller said he was from Visa MasterCard and wanted to lower my rate. Told him we didn't have a credit card and I wanted to know the name of the company he was calling from and he started calling me names and threatening to come and rape me and that my government was a joke. I hung up right away. Pretty disturbing
This is more than likely a spoofed number, after the 203 area code the number is 051 which isn't a valid sequence of numbers. Probably a telemarketer trying to get around the DNC list as usual.
