Mermaid Pools And Hot Tubs

Poor service from Mermaid pools. I purchased a solar blanket from mermaid and they cancelled on me three times on dates they offered. When they did show up it was late and without the proper supplies. They gave me no instructions and when they came back to complete the job they said I had not taken care of the cover? This is the second time this year I have had terrible service from Mermaid so I called and asked for the manager, they told me he wasn't in and would call me back. I had to call back twice more and not one of my calls has been returned. Once again terrible service
