Not happy

Cartrack installed a device in my car on the 5th of January 2023 and I gave them a debit date to be the 25th of every month, but instead daily they try to debit and my account has no money of which now it has gone up by R617,66 and I have been calling them,seeing them whatsp messages reminding them that as agreed I get paid on the 25th of every month as I have told them, I even asked them to wait till it is the date I receive my salary, I'm ****ed with their pathetic service I'm getting now I'm deeply on minus with bank account cause daily they try to debit and there is no money yet, till my pay date. Cartrack has the worst service I have ever received
