Vumatel bad service

I have logged a call with my ISP about my fibre to home being down on Wednesday, when I followed up on Thursday with my ISP they said they can't pick up my reference with Vumatel and they logged a new call and escalated it. Friday I phone Vumatel and follow up with both reference numbers. The one (first one logged is showing another person info) the second one they have corect and then said it has been handed over to a technician and they will contact me. It is now Saterday, no technician called and when following up with my ISP they said they have the same message/update on their system, they where supposed to contact me yesterday and now they can only sort it out on Monday because there is no technician available over the weekend. This is ridiculous and really bad service. Please don't use Vumatel if you have another option because whenever there is a problem, even with installation etc, they are useless and slow. Not my first time experiencing this bad service.
