Should I fire my PM or am I overreacting?

[Dustin Beam]

So I got a couple full duplexes back in November where each unit is renting for around $1000/mo. Market rent for them is approximately $1500-1600 give or take. I made a plan with my PM to get the tenants through the holidays and have rent raised to about $1250. I asked the PM to let the tenants know about this in December so they could have time to plan and make a decision.

Fast forward to Feb 7th and I asked politely if the rents had been raised because online report looked like they had not. No response. I followed up a few days later (10th) in case the email got lost in the shuffle. No response. I texted yesterday, no response. 

Firing them has a couple problems. One, they manage 48 units of which I'm 50% owner, so firing them from my non-partnership properties could cause problems to my partnership properties. Not exactly fair to my partner when they are doing fine on those. Secondly, I used to self manage some of my property that I handed off to them Jan 1st. Tenants won't exactly like to go to another property manager already, so not real good for business in that regard either.

At the same time, I don't appreciate getting ghosted. 

Trying to make this a strictly business decision, but I won't lie that emotionally I'm bothered by what I consider blatant disrespect (when I've always been easy to work with).
