Honestly, I've used them from the last 7 years...I didnt think i needed to check because theres' never been an issue. When I got the certified letter from IRS thats how this all started. The last payment IRS got from them for me was Dec 2021. I recently made Jan and Feb 2022 payments via pay pal. I show the money left my account but never made it to IRS. Filed a claim with Pay Pal...already got my money back.
