Upgrade and recording

I am not happy with the level of service that I have received from Vodacom. on the 7 August 2021 I heard an upgrade done on my data bundles which I told the consultant on hand that I don't want to do and upgrade due to that they are busying installing fiber in my complex and they said it wont be a problem they will just upgrade me from the date bundles to fiber. now I called for the upgrade for fiber they delivered the router and they don't want to cancel on the upgrade done which I was told it wont be a problem I have asked for a recording I have been calling Vodacom for the passed week and there where no notes on the system I spoke to Nikita Moodley said she will escalated to the manager and she will call back but no luck . when I call they send me to this department and that department and still not receiving any assistance.
