Not worth it to just ignore?
I just called the number to check it out for you , and I said someone tried to call me a few days ago from this number, Indian rep was nice, asked me for my business card number or SSN, said we have 4 questions we need to ask you ,1-Does your business cash checks? Does your business sell money orders in excess of $1000 per day, forgot the other 2
I do not think you have anything to worry about .
