I’ve crashed into these clowns who can only be an impersonation of a company who have a website but their number is no longer active at all and I can only assume the company is no longer in business.
It may have been a scam going back years in itself as the name Debt solutions 123 has popped up since 2015 associated with robocalls and scams
The real company website is here
https://www.debtsolutions123.com/
They claim to be debt solutions 123 on these numbers
5615323496 Debt solutions 123
8184749621 Debt solutions 123
8184749622 Debt solutions 123
