These folks never answer the phone and voice mail goes unanswered. My neighborhhood association has our yearly fees due on 2/1 every year. This year Heritage mailed the bills on Jan 3 2019 and dated them as 12/21/18. They showed our due date as 1/1/19 and we just started receiving the letters in the on 1/5/19. They mailed them after they were due! I have been calling them all morning and they will not answer the phone nor will it go the voice mail now.
