The operations manager of my small business was duped by a company for paying for their "services" to "help us in growing our business". Their people rushed into our offices, spent about two hours looking through our financial records, and left. Weeks went by and numerous phone calls were made, but no one ever returned any calls. Then one day, we received a bill for $100,000. Yes, one hundred thousand dollars. When called to dispute the bill, we were transferred to their "legal department". We were told that whether or not we were happy with their service we were still legally obligated to pay the bill. My business manager then set up an arrangement where she sent them The total amount, in post-dated checks. Recently we were contacted by the Illinois State Attorney General's Office and asked to become participants in a lawsuit against this company. Since there were no real services ever rendered by this company and because we are now involved in litigation against this company, do I still need to pay them?
