Vox - terrible & non-service

Terrible service! I had Fat pipe fibre installed and all worked 100%. I then moved to another house, and had the ADSL option installed as I didnt require the large 40/40 fibre line anymore. All went well and Vox sent me the ADSL router etc, and indicated on email that the courier will also collect the Mikrotik router from the previous address' fibre, as I no longer need the Mikrotik router. Needless to say the courier delivered the ADSL router but didnt collect the Mikrotik and Vox is now charging me R1200.00 for the Mikrotik that I can't use and don't want! I have been trying for several WEEKS to get a response from them and have send numerous emails and still no response. They also sent me a letter informing me that my services will be terminated due to non-payment...but the more I want to have this resolved, the more NO-ONE gets back to me on this. I need internet at home as I also work from home. I've never had issues with Vox before until now, and I am ****ed and dissapointed to say the least!
