Bad provider and not proper communication

My journey with this rotten provider started March 2021. September 2021 I told them I'm relocating and they must cancel my services because they wont be able to connect me with my new address. I got the email from Natassja Naidoo on 21 September 2021 that the router will be collected and I must send the collection address which I did. Up until today they never collected the rooter. So I've cancelled the contract and I was informed about the penalty fee of R2415 should you cancel before April 2022 on the 12 month clause. I've send the accounts department an email February 2022 that I will pay this account R200 per month because I am not having the funds once off but I've started paying them December 2021 already. R200 per month. I didn't get any reply. 26 February 2022 I received an email from natasha pheiffer stating no payment was received and this is the handover process. I've emailed her the proof of payments I've made. No reply. In April I was billed R1200 for this rooter that they never collected. Who's fault is this that they never collected it as I have send them the address? Now I must make sure it gets delivered to them and who's going to pay for the parcel to get delivered? They even send me an email 12 May 2022 Default on outstanding amount and handed over. How the heck can they just go ahead and hand people over that's having a payment arrangement with them and It is not as If I have skipped them one month. This is really pathetic and I really hope people stay away from this poor service provider as they are just out there to rip people apart and playing with my credit record. My consumer rights has been violated. And they still charge me monthly interest on this overdue balance as they're calling it. this is really insane and I am soo disappointed in Vox. ****** *****s and **** service! I regret the day I ever signed up with them
