This company claims to provide QUALITY SERVICE. Hah! Just try to talk to a customer service representative. All you get are recordings, and repeated requests to enter mile-long numbers. This company does not have any human beings. No matter what number you call, you will get recordings.

How could my check for $300 be declined by KMart (thru Telecheck) when I've got $15, 000 in my checking account?

I'll never know, and I'll be damned if I make a purchase at any business that uses Telecheck.
