Complain

Last year March I took a contract cellphone for a period of 24 months, this year from (July, August September) I failed to make a payment on the 22nd October I called that particular company to request a settlement fee indicating that I want to cancel the account and I've made the agent aware that my account is currently in arreas he should calculate the arreas amount and whatever that's left off for me to pay to cancel that account (premature quotation was provided to me with an amount of R1126, 24. The person who was assisting me agreed that it does include the arreas amount. Okay on the 23rd I called again and explain the very same amount and a new quote was provided to me and I explain to the agent as I did to the previous one regarding the status of my contract. I made a payment on the 24th and I sent proof of payment along with the cancelation quote signed to their cancelation department. I kept on doing a follow up into why the sim card is still active they deactivate it. I didn't get clearly only the past week when I called in I was told two different stories by people in different departments that I was only paying for the arreas amount while another said I was only paying for the remaining months. I got a call today that they won't close off my account as the arreas amount are still left unpaid, I told them I won't pay and they should listen to their call recordings please advise me on a way forward. Thank u in advance
