Extremely poor service

Cartrack failed to debit when they were supposed to on banking details that I provided them with. Then they requested a manual payment which I did only for them to send a tracking debit without my consent, which was successful as I had funds available in my bank account. This then meant I paid twice in the same month((Feb). I then called in beginning of March to request a refund of either the debited amount or what I paid via EFT, I was told they would pay back the EFT because it was less that the R219 that I paid because I was apparently late with the debit order so they subtracted some fee! Today is the 24th of April and I still have not received my money back and every time I call I get sent from pillar to post with no response and today I was told there no manager or superior to process my request and will have wait until next week Wednesday…this is sickening considering I did my due diligence. I do not recommend this company!! Extremely poor servuce
