Ruthless Giant Vodacom!

I took a contract in 2018, a buy one get one free deal. The contract ended in August 2018, I put a notice 2months earlier that I won't be continuing with the contract. I recently discovered that contract was handed over, to my suprise, the 2nd 'free' fone was a contract phone. I tried to go through the call center and I have been sent from pillar to post. Whybwas I handed over without my knowledge, when was I called to be informed about the nonpayment of the account? Are recordings available... I want to see the copy of the 2nd contract, and how come vodacom does not inform clients of the end of their contracts??? My life has been putbin hold, I can't apply for credit, all because of R279 rands! I need answers, I want my name removed right away from rhe said list! Vodacom how do you not take care of the very people who make you Giants in the JSE! I have realised that your call centre agents take people's issues for granted because the Company cares less and nothing much happens to the Company besides them gaining a lot of undeserved money from those who Support the business, Imagine! I need urgent intervension .
