Vumatel does not want to fix my wifi but i have paid full money..

I am paying every month for this Wifi but I have not had service from last week.. I work for home and I have had to use extra money out of my budget to buy data.. The customer service is horrible and they are not reachable on the phone... I refuse to pay a full bill end of the month due to the amount of money I have spent on Data so that my laptop and other devices can keep running around home.. I need my wifi fixed today.. Tomorrow is Monday and I need wifi to work!!!!!!! If they deduct money from my account end of the month, I will report thus company for ********.
