Very disappointed VOX telecoms

Very disappointed, The beginning of January I signed up for VOX Fibre after completing all the forms. A few weeks later a UPS device arrived via courier. I put it in the cupboard still sealed awaiting installation. We are now in March 2023, I still do not have the Fibre I requested and have been billed R 137 per month for a UPS device that is awaiting installation and remains in the cupboard. I have contacted their accounts department who transferred me to sales to fix the problem but Sales will not assist as the account is on hold. I cannot and will not pay for something I cannot use. Vox has now cancelled my service ... but I never had any. How can a service company be so ***********.
