Vumatel disappeared

I have an open escalation with Vumatel. I've been without internet since the 9th of September. For months on end I've had speed issues sometimes less than 1MB, the internet gets cut abruptly repeatedly. Technicians have been sent to my place by my ISP on 2 occasions, it was discovered that the actual Fibre cable has broken. Since then (9 September) Vumatel has given me the run around, reinstallation was supposed to have happened yesterday (12 September). We've been calling and calling, finally got hold of a lady which said she would call back to confirm what time installation would have taken place, we have gotten no feedback. I've resorted to contacting my ISP which has escalated the matter twice, it's now been escalated to Vumatel management and still no word from them. They have vanished. When calling, nobody answers, they have just disappeared.

Both my husband and I work from home and he is studying part time as well. Our data costs are sky rocketing, not to mention having to drive to family members to use their wifi which isn't always possible as we have to work at 1am/2am if need be, we're also having to drive to the office which is over 100km away. Our internet is paid for the month of September! Yes we pay our ISP, but surely Vumatel gets paid at the end of the day. This is totally unacceptable! I am fuming at this horrid customer service!!! I don't know what more to do.

I demand to be reimbursed as this is not what I am paying for!
