Impossible to get things resolved with Vodacom, non existent service

Lets try this method as Vodacom does not resolve queries via their call centre number, social media or email. I done an online upgrade on Tuesday and they said I will get a confirmation SMS shortly. I never received that and this said upgrade that didn't happen yet, is already on my latest bill. How the heck can I be charged for something not received or actioned? I have had a Vodacom contract for twenty seven years and each year, their service gets worse. I want my upgrade that is in pending status cancelled with immediate effect and want confirmation that this has been done. I wasted hours on the phone since Tuesday and even wasted fuel yesterday, to drive to a Vodacom store, hoping to get this resolved. Not even the store could assist me. Vodacom is making things very difficult for the very people that are keeping them in business, their clients. Phoning the call center, one person will tell me to phone this number, I then phone it, only for that person to tell me no, phone that number. It goes on and on like this. It seems that even the staff do not know which numbers are correct for their own departments, to give their clients assistance. I am now done with them and will move all three my contracts to a new SP.
