Vodacom Losing integrity and level of service

I want to advise people not to be fooled by Vodacom.As big a company as you assume they are ,you will be disappointed .Their service is horrific.I am not sure whether I'm more mad at the actual issue or the fact that it's coming from a company like Vodacom who people trust to give a certain level of service. They are billing me incorrectly for something agreed upon telephonically .Basically a Fibre contract taken on a Black Friday deal.They are currently not honoring the deal and charging me around R400 per month more than agreed upon.Lo and behold they cannot access the recording of what I actually signed up for (It was done telephonically) But they can tell me the date etc.(Excellent CPA case there)After a frustrating few calls I was advised to go to a Vodacom store for assistance as they might be able to pull the recording etc.I was also advised to maybe contact sales. Imagine Vodacom Sales telling a customer that there are no managers on the floor currently to assist and that I should call back.Wow.Not having a manager available is bad but not having the decency to ask a customer for their details to get a manager to assist etc is worse.Imagine a company like Vodacom with all their systems cannot assist me constructively.I am totally disappointed but equally amazed that this is a company that people trust without blinking twice
