Diamond Parking reply on 5/19/2010

I got a standard business reply email on 5/19/2010:

Thank you for providing me with an opportunity to respond to your concerns.  I have read your e-mail carefully and would like to note the following.  We provide an enforcement service to the property owner at this site and have posted parking rules signs that indicate that it is a violation of parking rules to park in the lot and go to another place of business. We did received your letter on May 5, 2010, however we did not have your contact number to contact you.    Our enforcement officer noted that on February, 2010 at 7:19pm and 7:21pm the drivers parked their car in  the lot and left, this is a contravention of these posted parking rules. Without any receipt we are not able to cancel these tickets.   Our agent has offered you $57.50 for each ticket to settle the account.   Please contact our agent at 604-681-8797 ext. 2 to make your payment.

I just replied with the following:

I don't agree with your enforcement officer.  It's outrageous to give ticket without any evidence and apparently with bad intent.  I cannot pay for something that I did not do.  In my letter previously and the letter to Better Business Bureau, I've indicated my position clearly.

I understand your company's procedures as well.  Since it's the enforcement officer's mistake, may be we can get together with the enforcement officer and solve the problem together.
