Telkom agents are giving us incorrect information, they only care about making sales.

On the 05.07.2019 I went to Telkom shop in Cavendish to repair my phone as it was insured , I was told I will have to pay service fee which was a lot of money. He did not even advise me what was the fee to fix my old phone was even though it was insured, as he was busy up selling. He told me I do not qualify for an upgrade as my contact was 11 months old. So Wilfrel advised me to take a new device , he told me I will pay extra for a new phone and insurance BUT will continue with my old contract. I agree to that because I knew I'm finishing my contract next year 2020 and continue with the new phone and insurance. Only to find out he renewed my old contract , went to the store on the 07.08.2019 and the Agent was shocked to hear that or he was pretending, so he gave me only one option to return the device , and i told him that is not the problem.He became very rude, he then logged a call and told me I will still have to pay for the new phone even if i return it. Told him that will never happen, I'm the customer that was given incorrect information and it is not my fault. All I want is Telkom to fix my contract it must end 2020 not 2021 the I can continue paying for the new phone and insurance .The reference number for the call was ***5 no one contacted me yet. please help.
