Best Maintenance Refrigerant in Tampa FL

In the past I have had good luck with this company, but I won't be using them anymore. I had scheduled a routine service for my AC and I had to wait a month, which is no problem. I work 2 jobs and have to ask off and and I did that, just to have them cancel my appointment the day of. I refuse to have to take off of work again, because I lose money when I do. They would only offer me appointments from 11-2, and I am at work during that time. This service was paid for in advance by my membership with them......I will no longer be a member. I have paid for a service I will not be receiving. I will NEVER use this company again. I understand emergencies happen, but I shouldn't have to pay or lose pay due to someone else's emergency.
