I inadvertently paid an Inform Diagnostics invoice...
I inadvertently paid an Inform Diagnostics invoice twice, which i didn't discover until I was preparing my tax return in February. I wrote to them immediately, with copies of the bills and cancelled checks. They did not reply. I wrote again in April. It is now June, and I have still had no reply. You can be sure if they billed me and I hadn't paid it in four months, they would be pursuing legal action against me. This behavior is unethical and unprofessional, and I'm reporting them to the Better Business Bureau.
