*** mweb?

i signed up for mweb fibre as i am customer of theirs for more than 15years, they said the in the promo the installation and setup and one month was free, after installation i received a bill for almost R4000 i phoned them and they said they shall correct the issues, a week later which is today 22 June i woke up to no internet email gone, they just cancelled everything with no contacting me, i phoned them they said they will contact me before 9h30 and it would be sorted but still nothing emails are not working internet still off, when i phone they answer and put me on hold and then the line drops. this is not good, they don't resolve my problem been more than a week and nothing. they just cut my service and still the amount of almost r4000 shows due. and the more i try to get this resolved and they not assisting the more angry i get.
