Pathetic service! Been without fibre for a week now, no resolution

I'm so tired of following up, honestly.

You guys should change your slogan to "we apologize for the inconvenience caused" because I've heard it more times than your actual existing one (whatever it is).

My punishment is that I'm brand loyal. No one else would put up with this mess.

After all the hurdles I had to overcome to finally getting my fibre properly installed and up and running, now I'm sitting without any fibre connectivity for over a week. The guy my case has been allocated to (a certain Tapiwa Jacob Mudzongachsio from your FTTX team or department or whatever) , for him to assign a field technician to come and resolve my matter, is AWOL or MIA or just plain avoiding my case. I have been calling in day after day since around the 10th of this month, still no connectivity!!! It's been troubleshoot after troubleshoot and escalation after escalation. Results? ZERO!

I'm exhausted, actually. And my own superiors are tired of hearing of my internet woes!

So what do I do guys? To top it all off, I'm being billed as if nothing's wrong. YOH!

What else do I need to do to get my matter resolved?!? Kindly advise.
