Shir ISP service

from the 1st June my fiber has being off I sent a email and called to get help though told me that vumatel cancelled my line ad you working on it I had to send emails everyday asking for feedback and nothing. I then emailed vuma myself they said nothing is wrong in there said. and when I emailed you guys still nothing I then het billed R619 and I didn't use my fiber at all it was off. and when I ask support for help nothing I email accounts nothing mo help I rather get a miss call from a private number and the get a email saying we tried to call you. and now again still not resolved and fiber off works service ever. I am tired of back and forth the you treating me with handing account over and yet you don't fix it dashfiber is **** really
