VODACOM FIBRE - why is it so difficult to cancel my contract?!

Vodacom Fibre - here we go again. I have been trying to cancel my Fibre for a week already. Sent an e-mail a week again, still haven't received a reply. Then I decided to call the call centre on 13 August - it took the woman 30 MINUTES to log the call. She said a technician is supposed to call me within 48 hours to cancel my fibre. Here we are on the 18th and no call yet. Called again this morning and the new consultant said nothing has happened with my case and it might be because technicians don't work over weekends... so what happened with the entire Friday and Monday?? So sick of bad service from Vodacom. I JUST WANT TO CANCEL MY FIBRE, why must it be so difficult!?
