Zero feedback on installation date

I have order a fiber connection for my residence about 3 weeks ago. The order was approved by Home-Connect(HC) shortly there after. So with a 10 days of not hearing anything I mailed the Sales team, which was very eager to get me to complete the papers signed. NO feedback.

I logged a ticket on their online system this morning(before 8am), to enquire on what the status of the install is. I need to know this, since I work from home and I need to be online and connected to customers during office hours. NO feedback.

I work in IT and understand complications related to venders and so forth, but all I want is a date for install. This is not how I would like to start my Fiber experience.

HC, after about 3 weeks of an approved order, the installing company should have on a list and have a date on which to install. I need this feedback ASAP please!
