VOX Telecoms service is very poor

Vox telecoms charged me a full month for a UPS which is not working, I reported the UPS first week of January till to date nothing was done. They called me yesterday(3 Feb 2022) at 11:59 am asking me if I am available at my house they can deliver a new UPS at 12:30 pm, I told them I’m not in the house and no one is available to assist - so we arranged that they’ll come the following day(4 Feb 2022) at 8:00 am - I delayed going to work and waited till 10:00 am No phone call, No feedback, No delivery...called them to track the delivery I was told there is nothing they can do from one of their dispatch departments all they can see from their side is that the device(UPS) is yet to be picked up and they’ll send an email to the lady who called me and I demanded they call her while on the phone because they did not want to give me her contact details, they couldn’t get hold of her and they can only follow up with an email...the lady’s name is Natalya Pillay, her service is very poor, since the day I called to report, No email, no phone call or no any form of feedback from Vox, I am the one who always call everyday, every time I call they put me on hold for hours or sometimes they don’t have Ben bother to answer their phones
