VODACOM FAILING TO DO A SIMPLE THING - SIM SWAP!! POOREST SYSTEM IN PLACE

My phone was ******. I have been contacting vodacom to make a sim swap, at first I was told my number is still under contract, even though the contract ended 6 years ago and my Sim has been on prepaid since then. I am being taken from Pilar to post, I was told to come with my mom as the contract was under her name.. I drove from Gauteng province to Limpopo only to still not get help! When I call VODACOM CUSTOMER CARE they tell me to go to vodacom shops, when I get there, the consultants tell me they're not the relevant people I must call Customer care! It's been a frustrating 7 days.. VODACOM System is the most poorest ! I was asked security questions, at first I couldn't remember things such as "the last recharge amount" then I got my bank statement as I always buy airtime through my bank app and got the right amount, but their system still says it's a wrong answer. One of the consultants even told me I am not the first customer, there had been 2 more customers with the same problem the previous day and they're also failing to assist them. Such a big company with such *********** employees and a poor system It's so disappointing. I am expecting important calls from that number and here I am, frustrated, not helped and left in limbo! Very very disappointed!!! Can VODACOM PLEASE IMPROVE THEIR SYSTEM AND TRAIN THEIR STUFF! This level of incompetency has cost me so much fuel money with doing ups and downs trying different vodacom shops!! I am still waiting for the Sim swap to happen! I hope someone will contact me and help me!! The cellphone number I need a Sim swap for : ***
