Stop mortgage payments due to bad HOA?

A have a condo in Orlando, Fla. Lost value from $262k to $120k. But the HOA is the real problem. These scumbags charge $500 for bringing in a renter. I had an issue with them and they never responded, just added another fee instead. That is when I stopped all HOA payments and mortgage payments. I could work something out with the bank on the mortgage, but it is the HOA that is the problem. I am done with the greedy HOA therefore have not paid anything more in a year.
