Who called from 3474344439

The person name is Robert Williams they keep calling me sending email that I'm going to be arrested in 48 hrs I don't pay them 13,000 and that my SSN will be placed on hold by the US Federal Government they said the FTC is pressing charges against me 3 serious allegation 1.violation of federal banking regulation act 1983 etc etc....is this a scam are what.....

Yep. Phone is not a legit way of letting you know. Tell them to send it through USPS as is propee

I keep getting emails in my spam saying his name is Robert William and that there will be an arrest warrant out for me and I will go to jail if I don't pay them over $13,000. Also, that they will notify my work, bank, ect.

Just like phone, email is not the proper way to let you know-see my post above

Yes they said they will also notify my job put a hold on my bank account etc
