I received several phone calls from this number and asked for money, please can somebody tell me how to stop this.

Block the number or assign it a no-ring ringtone or buy a whistle or air horn and blow their ears off?

A fake law/collection agency. They call you regarding alleged lawsuit, and solicit your credit card number to supposedly settle the debt.
They tell you scary-sounding legal b00lsh1t about losing your job, paying $10k in court fees etc.
Those kids sound like they're undergraduate law students.
They introduce themselves under American sounding names, almost surely fake, none of those kids can speak fluent English.
When you start asking straight questions they get arrogant and turn to personal intimidation.
Don't give them any info!
Beware, they got your SSN # along with your name and mailing address!
As per my investigation, they obtained the personal info from Cash America Net Holdings, LLC.
These kids might be employers of Cash America who illegally access and misuse the customer's private info.
I notified the law enforcement regarding attempted identity theft and private information misuse.
Everybody who received a call from them, i suggest you do the same.

P.S. If you wanna have some fun, just call these kids back and tell them about the felony of identity theft, these little scumbags are really funny on a rampage.

I received a call from these people stating there names are Attorney Alex Williams and Senior Attorney Shawn Woods stating I owe them some money from an alleged lawsuit in the amount of $1,$65.35.  I was going along with this until I thought about the (347)229-1908 number calling and they was the ones that informed me that it was a scam.  I am calling Law Enforcement on them.  Another number that they were using are (760)239-9098.

These people are going down.
