Comfort Control of SLC, Inc. They told me I needed AC repair parts that weren't needed. Port Saint Lucie Florida

My complaint is against Comfort Control of SLC, Inc. located in Port Saint Lucie, Fl 34986.  I had them come out on a repair call and they were supposed to clean out the clogged AC drain lines.  They told me they applied chemicals and pressurization to clean out the lines but they never did.  On another visit they told me I needed a new evaporator coil.  On getting a second opinion from another company, I was told my evaporator coil was in perfect condition.  In my opinion Comfort Control of SLC, Inc. is not to be trusted.
