I had a very difficult time getting in touch with them. I did finally get an email reply and they did take care of repairing the crumbling concrete by the unit I own.
I was told this is an emergency number answered 24 hours a day - try calling it. The emergency number is 220-9705. This is the office number - I called it several times, too.
(608)222-9580
I am not impressed with them at all. They have not taken care of the other matters I emailed them about. Of particular concern was when the hot water heater was leaking in the unit I own (our son lived there). This took place on a Sunday. We had to call John, the man that used to care for WTC, in order to get anything taken care of.
