mad as hell

I have signed up with vox and my fibre only got activated on the 7th november yet when they sent my bill i had to pay over R1200 which does not make sense as for 6 days of november i have had no fibre anyway i paid the bill based on what they sent even though they over charged me. to my surprise my fibre was off on the 30th november even though i paid the full amount i sent a message on Facebook and they said they will contact me. its the end of business and still no one contacted me and they not even going to compensate me for them making an error. they quick to send the over charged bill but cant fix the problem so fast. i am completely ****ed at the service and i just started with them.
