Bad service by Vodacom

Good day...I am very disappointed at Vodacom service, they activated COVID relief on my contract without my permission when I called them they told me it was activated by me ,the second time they told me it was activated online ...firstly I didn't know of such thing existed and when calling I wanted to do an upgrade because my contract is due now they are telling me I can't upgrade because I am due next year May which is new to me...I upgraded 06 July 2020 and it was a 24 months contract now they telling me it was extended due to the COVID relief....I asked them to remove it I called 3 times they told me I am gonna receive a call within 24-48 hours but nothing...I have had contract with Vodacom for six years now I never had this bad service now what I want is to cancel both my contracts with them and get it from another network because the treatment is very bad and their service lately very poor
