Fibre Complaint - Vodacom

I signed up for Vodacom Fibre 10Mb up & 10MB down the package in August 2020, while the fibre infrastructure installers were still busy with the network project. Vodacom offered me an Interim LTE of 100GB to use until my fibre goes live. First 2 months for free, thereafter paying R 599 until the network goes live. Now that the network is live, they cannot find my order, although I have the router with the interim sim LTE in my possession and using it since August 2020. My order number: SO*** completed with Vodacom sales person Anton Malauleki. I phoned Vodacom`s *** number spoke to Joanne who informed me I signed up with another ISP. Sorted that problem out with Metrofibre, they thought I have signed up with them, although they only did a survey on who will be interested to have fibre. Received mail from Metrofibre confirming that my supposed order was revoked and that I can proceed and sign up with another ISP. I have unplugged my USB LTE stick from Vodacom`s router and stopped paying for it on 28 February 2021. I called Anton Maluleki this morning, now he informs me, that he cancelled my fibre order and sent my details to MTN, all out of his own accord. I also have problems cancelling the LTE now, which should not have been a problem, as it was supposed to be cancelled automatically when the fibre went live. Oh, I am so fed up with this bad to worst service. What can I do to sort out this problem?
