I think you could beat them on the penalties and interest on their mistakes but not the other stuff.

I sent a check for my taxes once and it was never deposited so I had to pay a penalty. They lost it. However, how could I prove that I sent the check?

One time I had 5 condos all in a row. The same name and address was on all of them so I got the tax bills all at once in the same envelope.

One year only 3 came. I paid them thinking the other two would come shortly. They did not and I forgot to keep looking for them to come thinking in the back of my mind I had paid them.

A relative called me and said two of my properties were going to be auctioned off. I had to pay $1000 each to some slimeball lawyer to redeem them.

The idiots had sent two of the bills to another address and they were returned. Then they made no effort to find the real address.

How did two addresses out of five change? Could a lawyer pay someone to change the address?
