the worst service provider

I got a cellphone contract with vodacom since 2019 if I'm not mistaken and I am still paying for it!! I have never paid for a cellphone contract this long its unbelievable !!! I had a bad experience since the day I signed a contract with vodacom, first the lady who assisted me ******* me into getting an open line, she **** and said its the on I qualified for which caused the account to fall into arrears. I finally paid it up this year, called vodacom in February to find out when my contract will be ending, the agent I spoke to said the contract is ending in June because apparently I was on some covid relief that I did not even ask for and I was still paying there was no relief. I threw away the sim card I have not been it for months now I am paying for something that I am not using. The consultant whom I spoke to in February suggest that we change the package to something cheaper since I was not using the sim card and she said contract will end in May but to my surprise when I called on Friday that said that the contract was renewed and will end in 2024 whereas it was clear in my conversation that I wanted to get rid of vodacom as soon as possible. How the hell can I pay for a cellphone contract for 5 years this issue needs to be sorted
