Breaking the law - Consumer Rights Act 2015

I am not happy with my mobile phone (Huawei P8). The battery doesn't even last me 24 hours. I brought the phone back yesterday (04/03/2016) to the Woodlands branch in Pretoria but they were not prepared to help me and said I need to go to the branch where I signed the contract. They gave me an reference ID (***2). Today I went to the Springs branch were the contract was signed. THEY CANCELLED MY CONTRACT BUT BILLED ME FOR R9000-00. I DON'T WANT THE DEVICE BECAUSE IT'S FAULTY AND I DON'T WANT A CONTRACT AT TELKOM. They just took the phone in for repairs. I don't want it repaired, I want to give it back and cancel my contract WITHOUT PAYING R9000-00. IF YOU DON'T SORT THIS OUT I WILL TAKE YOU TO COURT. I have rights according to the Consumer Rights Act 2015. I had enough of service providers praying on customers. <br> BAD SERVICE!!!!!!
