When asking for payment, i was told that we made errors and that they did not owe the money in the tune of $6000.  I doubt we made that many errors.  when asked for proff of payment, i was told they did not have the time.  They said my book keeper did not know what she was doing but still refused to provide any proff thier claims of payment had been made.  I was told they did not have the time to do our book keeping, that it was my problem.  Now i am being told after sending a certified letter demanding payment that they where going to give it to their legal department.  Good, maybe they will have the time to defend themself .
