Worst ever.. They just want money and cant rectify peoples accounts

Im not really one to write up bad reviews but Vox Customer Service or accounts has HORRIBLE customer services! They dont phone to communicate with u.. U pay ur UPS hire dillegently every month and because u defaulted once on the wifi because u moved premises end of May becausr u had no choice they want to cancel everything for a small R700 (which in fact was paid up in Sept) and then they go on to send u an account of 13k because u refuse to give back something u been actually paying for and will continue to use! They dont even call u.. And when u call them they dont answer or at least the designated department doesnt answer.. I had a fibre line of R750 and a Calling service which was R180 a month plus 2x Ups's which in total is around R400 a month for both.. Every month since end of may o paid the Voip and the UPS's i just couldnt afford the wifi as i had to already fork out for a new one at my new place. But still every month i paid.. Anyways they cancelled my VOIP because i didnt pay the remaining R700 and but i still paid my VOIP. They couldnt even take that R180 as part payment then towards the wifi bill. So june july august and sept i pay voip. Also come sept i paid an extra amount in to get teh wifi bill outstanding paid up. Then they automatically cancel my UPS contract which still had months over and want to charge me penalties of almost R13k for not giving back their hardware.
