Vodacom contract

Hi my name is berneleen oormeyer i had 2 contract phones with vodacom witch was going to finish in march 2024.Last year the 1st of october i upgraded with one of the phones so my plan was to terminate the other phone.On February the 7th i received a call from vodacom explaining the great deals and i can get R149 airtime for 24months i told the lady i am not interested since ive already done an upgrade she told me thank you but if you want the upgrade you can go to any vodacom store i said ok thank you i dropped the call.So i went to terminate the contract the lady in store told me but there was already an upgrade done on this number i explain to her that i have never given any consent for the upgrade. She gave me vodacom customer care the kept on saying i wil receive a reverse message then i must call again for cancelation. Ive spoken to so many vodacom consultants sometimes they wil tell you about chat box tobi.Im realy not happy with the service
