I live in St. Louis and this is a St Louis area code but it's really the people wanting you to cancel your current merchant card provider so they can supposedly give you a lower rate.  Asked for the owner of the business, but I told them they were out of the country in Europe for 3 weeks,  caller said "Ohhhhh. how nice" somewhat sarcastically. Said she's call back in 3 weeks, I hung up and blocked this number.  I probably get 30 of these types of calls on a weekly basis.  Sometimes I tell them to call Macy's, or Target, or Wallmart or Walgreens and ask them to change their merchant card providers.
