Vodacom does not understand the meaning of "Customer Retention."

Vodacom never ceases to amaze me with their pathetic service, for a supposedly leading Telecommunications company their customer retentions is pathetic. I am due for a upgrade but retentions does not call me, i noticed that on the 01/04/2023 that my data plan on my package was not loaded only the Top up airtime, I then spent the entire day trying to get an upgrade sorted out but as usual from Vodacom i had to be transferred from "Pillar to post", sent through to upgrades (they can't do promotions) transferred to online (neither can they do promotions and they awaiting for systems to update with new list), then transferred back to another department. but all the time in between being transferred the call goes nowhere meaning i have to disconnect and call back. I even tried the upgrade option on the Vodacom app and selected "Call me back" and guess what i am yet to be called. If this is how Vodacom handles retention and values loyal customers, I am utterly disgusted but then again its nothing new when it comes to Vodacom.
