None existing customer service!!!!

How is it possible for Vodacom to fail on so many levels? 1. I requested my upgrade 27/1/2019 - still nothing received. Part of that the Courier apparently had the wrong number to contact me and after a request to update the details it was cancelled and sent back. How did they get another number to contact? 2. I asked to speak to a manager and was promised that someone would phone me, no one did? Will I ever be phoned? 3. I logged a Hello Peter Complaint and it was closed with a comment that i cancelled my request, even after saying that is incorrect nothing further. 4. I requested again for my upgrade after almost giving up, due to months changing there had to be special approval to get the same deal, that was done at R799, but received an sms to confirm the upgrade for R1132 or something like that, i indicated it's wrong...and still waiting 2 days later for someone to contact me.

Does Vodacom actually care, do they take customer service serious? I am a long standing customer with a few contracts, but still get **** service like this. Every time it's up to me to follow up and to phone to find out what is going on.
