Mike Jearle was a great technician, I was running a little behind and he stayed to make sure my Service was up and running again. Did the job quick and fixed all my problems.

Carlos was our technician and he was nothing but awesome! He was kind, dedicated, and punctual. For our service he went above and beyond to ensure we have everything working properly. The service Carlos provided already enhanced our experience with Astound. ☺️

My bill with Grande doubled in a single year, despite being a customer for almost a decade. They won't give me the cheaper rates they advertise online, and they demand to see personal lease documents if I try to sign up again. This is a terrible business practice. I am pulling Grande from all my rentals.

5-Star Review for Carlos (Service Installation)
We recently had an amazing experience with Carlos for the installation of our internet and phone service at Sendero Trace.
Carlos is, without a doubt, one of the most professional and knowledgeable service technicians we have ever encountered. Not only was the installation process quick, efficient, and perfectly executed, but Carlos went far above and beyond the scope of the required work.
He provided invaluable, detailed information about transferring our services and offered fantastic advice related to our small business and the home-buying process. He even shared recommendations for trusted local contractors for future appliance installation and side projects.
Carlos made us feel completely supported throughout the setup and demonstrated a genuine commitment to customer care. He’s an incredible asset to your team, and we highly recommend him to anyone needing installation or technical support. Thank you, Carlos!

I called three days into not having WiFi cause I assumed it was because of the rain, there might have been an outage.. but I had to wait three more days after astound cancelled my appointment…. Idk why. They had Timothy (thank the lord) come out here and teach the blonde how to fix this simple problem that I could have been fix over the phone… he was nice in telling me it was the internet box not the WiFi (internet was in the wall) as a non WiFi expert didn’t want to mess up!! thank you Timothy for being a great help and understanding!
