The customers don't like our new prices

I have been working for the same HVAC service company for the past 5 years.

About six months ago, a new manager took over our branch and made a lot of changes.

One of those changes is raising the prices of every single one of our services. For most of the time that I have been working at this HVAC service company, the price of a tune-up has been $89. This price includes the service appointment and a brand new air filter. When the new manager took over the branch and made changes, He raised the price of our tune up from $89 to $109. We never sent any information to our customers to alert them of the price increase. I’ve had a lot of upset people this week. It’s the perfect time to have the AC unit serviced, and a lot of our regular customers are making appointments. Last week, one of my customers sent me away when he found out that the price was $109. Yesterday, a customer refused to pay the fee when they saw the bill after the tune-up service was already finished. The guy was angry and combative and I honestly thought I was in trouble. I left without any money in my pocket, when the customer threatened to shoot if I didn’t leave the property. This job isn’t worth losing my life, so I decided to let the boss deal with that customer. I knew some people would be upset about the changes, but I didn’t think it would be this bad. We will easily lose some business because of our increased price list.
