Lakeside Landing Mobile Home Park review: unexplained charges

In December I set up an account at the new park portal, and had planned on paying online, but the system said I needed to add $43 to my lot rent payment, so I wrote a check. I went to the portal again in January and now I owed $86 extra, I wrote another check. Then I received an eviction notice, so paid. This month I am charged $12 extra, & dont know why.
