How Long After Burial Before You Got Service?

Metronet finally came to our neighborhood this year and finished digging & laying lines in September. I signed up at the first chance for service and then the T-Mobile acquisition happened. To date, no one has contacted us about installation, activation, or anticipated go-live date. My question to you is: How long after the groundwork was finished did you actually get to use your service? The only thing more annoying than the T-Mobile silence is the Xfinity bill we have to pay every month until fiber finally kicks off.
