Worst worst network and lying rewards Co contracts

I am so agitated!! Vodacom along with Mondo/rewards Co is the worst thing ever in my life! I upgraded last year october they initiated the incorrect upgrade . Actually they downgraded me at a highest fee then I had to call and remain on calls for hours to no assist after 3 months of them investigating they found i was correct they said they’ll credit my acc and also fix the error. That did not happen instead the acc was credited 4 months later after I called every month and their downgrade data would finish in 2 weeks for someone who works from home this was a huge inconvenience then I called in April and I took the 1tb gig from 1 of May this was still not done!!!!!!!!!!! Okay cool i call again in may shocked that the 1tb finished then I was hit by a shock that this was never done as the manager who was supposed to do this resigned???? Is this a joke Vodacom!!!!! Then they tell me to say sorry they’ll give me 100g promo and 50g what what to last me atleast till month end while they initiate the 1tb for next month! Only to find out in may that all the free things they said they gave me they then charged me 1k for!!!!!!! How on earth will I pay 1k for 150g feee data you gave me after giving less data than i was supposed to get for 6 whole months????????? 200g less due to their lying sales consultants! Okay cool in may rhey said they’ll credit and now it’s June and still no credit!! Every month since last year ocyober I have been on call with Vodacom and mondo/ rewards co for more than 3 hours every single month without a fail due to their incompetence!!! I am absolutely done!
