I get frustrated when businesses don't answer their phone. I had called them in the AM and got their VM. I didn't receive a call back until 7:30PM. I saw their reviews on Yelp and was going to give them a opportunity to quote a window tinting. The next call was to Eco and they got my business.
One thing that further concerns me when businesses don't answer the phone is what if I have a problem or concern. Them my only option is to drive down to them hoping they are actually working. To me that is a bad sign and I move on to another business.
The manager who called said they were so busy and couldn't get to the phone until that evening. Sounds like they are understaffed and that is another concern. Hopefully they can correct these issues and be the business the reviews talk about.
