A Tech by the name of Markus came for our service call, he was kind, courteous, professional and communicated well. He left his workspace clean and tidy after he completed his job and I would consider his service he provided 10/10. I highly recommend Markus and the company he works for! (Unlike every other service provider or restaurant these days - he didn’t even ask for a review, I was so happy with the result I asked how I could right away)Posted on Google![]()
