Vodacom worst customer service experience - Fibre and Mobile

Oh Wow(More a scream of frustration). It's been 3 months since I have opened a Ticket with Vodacom. Still no feedback, for 2 months I got updates over email the ticket status was changed to Updated, no information whatsoever. I have left the ticket to see how long Vodacom takes to resolve a ticket or at least provide actual feedback. The 1st line support is useless and I don't think Vodacom Fibe actually has 3rd level support. Vodacom personnel is supposed to be tech-savvy, but I guess they only need to cater to the masses in telling people what they like to hear. My concerns have now been going on for more than a year. First Vodacom Says they do not support WIFI Calling as it is not supported by 5G network. That is *******. I have seen this working over Telkom fibre. What makes Vodacom so special. Then I asked to get access to my Router. They apparently don't know the username and password and need to get that from the Vendor. This is ridiculous. My router setting has changed 3 months ago and my 5Ghz wifi channel is not enabled as Vodacom disabled it, but cannot enable it again. They told meI have to enable it in the Admin Console, but guess what. I don't have the username and Password. Because telecoms have a monopolized business in South Africa they can charge whatever they want and provide any service they want, because they are not a service orientated business. I'm am so tired of the way they do business. I pay an arm and a leg for Vodacom services (Mobile and Fibre), and yet they laugh all the way. We have no choice in our estate but to use Vodacom. What a disappointment.
