Miscap again. AGAIN.

This is like the 5th time.

Some background story:

My landline stopped working 2 weeks ago with the internet still working as usual. So I informed TM and asked to have it fixed.

Today, my phone line got fixed but guess what? I noticed my internet becoming significantly slower.

Check modem info page: Downstream 2048 kbps.

Call TM explaining this mistake only to have to do dozens of procedures like restarting modem, do speed test, do browsing test, do streaming test, download test, etc etc etc.

At the end, I'm told a technician will handle my issue.

Since it is such a common practice to miscap their users, is there a way anyone here knows of that can make this awfully painful process much easier? Like direct contact with technical team to solve the issue immediately? Rather than fumbling about doing unnecessary procedures when the issue is bloody obvious.
