Worst service ever😒

I ordered fibre through MWEB who's SP is Octotel and the has been issues since 11December till Jan 6th the fibre is not installed only to find out that there is fibre and router installed by the previous tenant. Even for the technician to be dispatched and activate the current equipment in my name its mission impossible. I work late shifts and I work from home but I cannot seem to get this sorted for a month now.
