Tracker took money from my account without authorisation

I have sent the following e-mail to tracker over 48 hours ago and have not received any response... Please reverse the amount of R1,185.39 which you took from my account on Saturday without any authorisation to do so. The amount of R1,250.00 was paid into my account by a client, which I had to then pay over to a gate motor repairer of that seller as soon as the money cleared. I had a viewing appointment on Saturday at 14h00 and when I got home and wanted to do the payment to the repairer, I saw that tracker had taken almost all that money from my account. I have responded to previous sms's from Tracker, saying no to debiting more from my account. Please reimburse me as this was not my money. You put me in a predicament. I tried to stop the debit order, and to dispute the transaction on my Capitec banking app, but was unable to do so. I am truly disappointed in Tracker's poor non-correspondence!!!
