I live in a gated community serviced by CSS. We have a bulk DirecTV contract with them.
Few months ago they forced me to buy Genie HR54 and Genie mini 4k because their technicians not trained to setup RVUs. Anyway. Because the lack of DirecTV 4k programming at that time I didn't noticed that he wired wired the 4k receiver to my 1080p TV and the 1080p receiver to my 4k TV. The guy used my tools to drill the floor and he charged me 100$ for the installation.

I've called CSS earlier this week to schedule an appointment so they can fix my setup.
The technician was supposed to arrive Friday between 9am-11:30pm. Around 12pm I've called CSS to see what happened. They told me that earlier this week I've called them again and the ticket is closed. I never called them back.

After a conversation with the supervisor he promised that he will call me back in an hour. You can probably guess he never called me back.

Now I know why they have all one star reviews. Terrible customer service.
I'm very disappointed.
