Telkom service

I app**** to change my internet from LTE to Fibre early October, firstly, Vumatel was the only option for me as per Telkom because of my area. they did their part very swiftly (around 19th October) , however Telkom did not bother to deliver the modem as per protocol, to date I still do not have the modem. I am being billed for a device (which I don't have) that was not revealed to me on entering this deal. I emailed them enquiring about the modem not being delivered. After a week of no response I called and was told they logging a call and was not surprised coming from the Rosebank Store. A lady then called a few days later, asked if I could come and collect the modem which I refused as I cannot be inconvenienced because of their incompetence, I need it delivered. To date (20/11/2020) I have not received any device but received a bill that is almost double the amount of what the contract was sold off to me. I really am so disappointed with the lady I spoke to 17/11/2020 as she did not even know what I was talking about firstly, and insisting that I have a device and the fibre is active :(. I am so frustrated because I could have gone to so many other service providers... and knowing I'm being billed for something I am not using or having any joy with it is just making me angry.
