Unsatisfied customer

I've been a customer of Vox from 2018, been paying for Vox voice + Vox fobi usage (uncapped), we received a normal Telcom phone and the technician took the phone with him (incorrect phone) and never received correct phone, this function was never set up and have been paying for this service every month and cannot use it. Every time you phone to rectify the problem you get transferred from one person or department to another (today 4x). We are paying for 500 upload and download and get throttled, then we need to phone them to reset or correct problem (up to 2x per month). According to my experience, Vox one of the worse fibre suppliers in SA and I will not recommend them for services. The last guy I spoke to today said he will transfer me to the accounts department and was placed on hold for 10 minutes and nothing happened. Again, I requested him management must contact me and no joy.
