DISAPPOINTED, FRUSTRATED

2018 I received sms's from Cartrack, showing me that I owe them R1100, then I called them in August or September to make arrangements on how to pay it, so they said I must pay 200 every month, so I started to pay in November 2018 until October, I've reversed the debt order in October coz I know I've finished paying the account, today some lady called Phindile was shouting at me telling me I owe 2600 I think not 1100 now and she was shouting telling me I'm laying I owe this money, and now I'm waiting for the recording of last year wen I made the arrangement, that lady was rude, ***********, Car track owe me 500rand and I want my money back
