Vuma reeping people OFF

I been cut off for full day now no idea why and Vuma is reffering me to 3rd party ISPs who i didnt even communicate with when i signed up for Vuma. I was told my debit is 16 Jan i been calling the so called ISP which sounds and looks like a nigerian fly by night.What these companies are doing is totally wrong.DONT SIGN UP WITH VUMA YOU WILL REGRET IT!
