Time to change Property management?

[Kah M.]

My property managers have been good overall but recently, they've been doing things that makes me question their judgment. 

• Billed me for an emergency furnace repair that cost more than replacing the entire furnace. My requests for an explanation went unanswered
• We had an eviction and the house was supposed to be clean and minor repairs made before a city inspection. I was told the work would be done before but all the comments made by the city inspector were the things that should've already been repaired (and the work was already charged in full)
• The house was placed on the market and rented pretty quickly. New tenants made simple requests which I approved. They paid a holding deposit. We stopped showing for 2 and a half weeks. On the morning the new tenants were supposed to move in, I get a notification from the utility that the bill was put back in my name. It turns out the tenants changed their mind because they didn't want to pay the pet deposit and wanted more work done on the house before signing the lease. I wasn't told about any of this. PM gave the tenants back their holding deposit
•  New deadbolts were installed on the vacant house for unknown reasons. We already rekeyed the entire house months ago. I explicitly told them to inform me before any work is done twice this year. 
• The house has been vacant for over 90 days despite their claim there are hundreds of requests for viewings. The house isn't listed anymore and I didn't get a response about why that is.
