David Haney's Review Sourced from Google
I have done business with ADL Call Center, and they do not pay their bills. It's virtually impossible to reach anyone live at this company, and they have a past due invoice from October 2024. My contact who runs the Call Center has ghosted me, and over less than $500.00. My personal opinion is if you cannot pay your bills, your not worth doing business with!!!

Their team steps it up whenever our business needs extra support and attention. Since we are a family owned business we appreciate them treating us like family and vice versa.
