Poor Customer service - Installation

For a company that is struggling so bad, it's amazing that they still allow interaction with existing customers to be so poor. I was supposed to have a new decoder installed on 14 Dec at 10am. 10h05 I was called they couldn't do it and we must reschedule, I asked if no-one else could assist as I had changed my plans to accommodate the installation in the morning. They said they will check and let me know. Since then I have heard nothing from them and the installation no longer appears on the website. After 15yrs I feel like cancelling, this is not good enough. You are struggling as a company and treating customers like they don't matter.
