The short version parking was a mess took over 1 hour to get the car moved that was parked in front of the garage. Garage is in a sketchy alley way. The neighbor told me I wouldn't be able to get my car in the tiny garage, even if I did I wouldn't be able to get it out because of all the cars on the tiny little street so we ended up parking in front of the garage like the previous car was parked. Then at 3am both the heaters had an error & it was cold so we messaged him asked what we do to fix the heater he told us pull the hose out from the back of the heaters and drain the water so we did that but no water came out my sister figured out we pick up the heaters to let the water come out so we did that. Then the heaters started working and we went back to bed. At 630am we woke up to the heaters not working again He told us we didn't let all the water out. We shouldn't have to maintain his heaters. Now he's trying to charge us over $500 for possible damage we didn't damage anything
