My service tech was awesome. I had a tight deadline & customer service was able to get a tech out ASAP. The only thing I didn't like was that i was told it was $62.00 minimum service charge I assumed if the charges for the extinguishers was less than $62.00 I would be charged $62.00 not the price of the extinguishers plus $62.00. I think that could have been explained a little clearer from customer service. Other than that I have no complaints.
