Worsts service ever!

Worsts service ever! At the start of applying for my 3 VOX lines I received my fist bill stating I had 4 lines. After a few weeks of arguing, I was billed correctly for 3 lines. A few months later I notices an increase in my bill to 7 lines. I emailed and called to try get this resolved. VOX has admitted the error yet I still receive incorrect bills, and threating phone calls to cut off my lines. I am now sitting in a position where VOX has cut my companies landlines, when VOX in fact owes me a few thousand rand. I would never recommend this utterly useless company that’s has in fact ****** from me and has now effect my business during this crisis by cutting off all my company land lines. NEVER use VOX their service from the start has been shocking and they are happy to just bill you what ever amount they want and then you need to fight to get the money back.
