I moved my support to Coolabode in August 2020 after finally tiring of the poor service from my original installer. Andrzej has helped me a couple of times since then with some remote control programming and a few issues with C4 and Sonos integration. And I recently worked with Kyle on another Sonos-related issue which ended up being hardware-related (old Sonos Connect output failed).
In every instance, with both Andrzej and Kyle, I received a very quick response to my initial request and great communication and service throughout the entire process. And their pricing is very fair.
I highly recommend engaging the Coolabode team!
