Invoices

Last month I was charged for something I didn't know and was told that I was informed about this which than I I did explain to them that the only charge that I knew about was if they found out that the tracking device was not an issue or it wasn't and tracker issue then they will charge me for that. Which then that got resolved but now I am being sent an invoice of the amount of R212,79 which I don't know why I am bring charged for this, it doesn't explain what this charge is for. Customer accounts number: CLI **********

Why would I recommend this company to anyone. Its really annoying how they assist customers
