Certegy Check Services

Has anyone else had a run in with these a**holes? Went to pay for my auto repairs with a check and had it denied! Call my financial ad visor and he said everything was fine on his end. Call Certegy Check Services and that is where the fun began!! They said Certegy Check Services denied me based on a “code 2, which states “although no unpaid check information is on file, Certegy did not have sufficient information available to approve the transaction, or this transaction exceeded a pre-established limit”. Upon telephoning the company they were rude and gave me very vague reasons for my denial. Finally they said my denial was not based off of any concrete information only statistical information. They would not inform me how to fix this problem, but that I could fill out a form with my social security number, bank account and routing numbers, and that I would then maybe not have this problem in the future. I will not relinquish any of that information to them for fear of Identity Theft. So now I will have to pay cash because most credit and debit cards go through this verification process also and because I would not trust some third party with my private information. This just seems like a scam.
