I filled out Mainstreet.com's intake form and was told that I qualified for tax credits, for which they charge 10%. Great, I thought.
My CPA later said that I shouldn't actually file this, but Mainstreet refuses to rescind their fees and wants to continue charging me monthly. Direct quote from their response after I complained:
"If you and your CPA decided to move forward in not claiming the credit, we completely understand, but we have fulfilled our contractual obligations in providing you with everything needed to claim the credit. If you'd like to cancel future renewals we can certainly do that, but there are 5 remaining payment cycles in the 2022 subscription that will be collected. Once the 2022 program is paid in full we will ensure you are not renewed further. "
This is unbelievably scummy behavior. Avoid Mainstreet.com like the plague.
