Dishonest company with pathetic service.9

I concluded my contract with Vodacom in Nov 2019, called in to cancel the month-to-month data i was receiving too and was moved to prepaid immediately. Today I tried to apply for finance and was declined because of my account with Vodacom that is in arrears... when i went to query this, Vodacom had not only not ended my contract but i was billed R1.00 for the month of Nov 2019 which was not communicated, R1.00!!!!! After i was told that everything is up to date and the contract is finished. I am still awaiting my settlement letter which i was told i would receive today but nothing. I paid your money in full and you listed me on ITC for a R1.00 that you never communicated with me. Fix it! I need that listing removed yesterday.
