VOX can't even help out one of their paying customers

These guys on the other hand also cant help me to resolve a issue as my own ISP that VUMA has created. I have opened 3 tickets with these guys as well where not one of them was resolved as i also just got told that my line is up and running fine. I have explained 3 times to their techs that VUMA has mixed up my lines and it like these guys are just to stupid to understand what my issue is. I am getting treated like i am the one that doesn't know what he is talking about as they know better. I have to pay R1412 pm for a service that i don't get and need to sit without internet. I have refused to pay VOX for last month and i will not pay for that month as i don't receive my service i pay for. I will request a refund for last month. I this problem does not get resolved i won't pay that account and i will move over to a other ISP.
