But Don’t Take Our Word For It
Matt was great. I live in Richmond and have a house in Maryland. I could not asked for a better guy. He was fantastic. He was the best. HE WAS BY FAR THE BEST SERVICE TECH EVERRRRRRRRRRRRRR!!!!!!!!!!!!!!
I cannot do justice to the overall quality of the service, but I also want to pay homage to the kindness and the generous treatment that I received, in turn, from Adam, Glenn, Justin and Will. It is my pleasure and indeed my responsibility to commend each of them and Blue Dot for having such reputable competent and committed employees.
I believe I found my go to company now. I will continue to use Blue Dot Services and will refer them to all my investors, friends and other business associates. I wanted to say Thank you again to all the associates I dealt with from Blue Dot. You guys really impressed me. Well Done!
We are a long time Blue Dot customer and have always been pleased with our service. The latest visit was no exception. Our service rep, John M. was prompt, friendly and knowledgeable. He performed our service check and answered all of our questions. He also left us printed material and price quotes on possible future purchases. We would be happy to have John M. as our permanent Blue Dot service rep.
