Insulation Continued

The main floor gets cold as I approach the exterior walls so I decided to take advantage of the tax credit and have spray insulation put in the band joists. My Uncle is an expert in researching home renovation and his instructions were to go with closed cell so I had the closest contractor, Fiberclass, come out and give me an estimate on December 9th. Aaron, who provided the estimate, gave me a good price and also some other tips about how to insulate (he agreed that the pink foam was the best option on the below ground exterior walls). I made the earliest appointment for insulation, December 23rd, which also fit my schedule perfectly since it was the last day of work for the year and also the day before I would be leaving for Indiana for two days - I was warned about the fumes. The appointment was 2:00-5:00 and when the installer hadn't shown up at 3:30 I called and was reassured that they were running behind, but would be there. At 9:00 I gave up after none of my messages were returned. Finally on Monday I got a call with apologies, a 10% discount and an appointment for Tuesday morning. I forgot to mention that my frustration was intensified because I had pulled the old insulation out to help the installation go quicker so this part of my home was uninsulated for 5 days.
Tuesday morning the crew showed up at 8:15, but had new dispensing containers and were missing parts. The installer promised me that one they had their office bring over the correct connections the job would be done in 20 minutes. Instead it took until after 1:00 and several trips from the office with new materials.
This is the data sheet that came with the material, it is what I wanted. I would be more frustrated with Fiberclass, but they must have lost money on this job given that 2~3 people worked for 5 hours and I only paid $210. Her's hoping that after the tax deduction this job pays for itself and the frustration in reduced heating costs and improved comfort!
