Unauthorised debit on account!!!

********** activity on my account!!! This company is the worst and wouldn’t recommend it to anyone! First they mess up my power steering while installing their tracking device, then they charge a R600 call out fee which I refused to pay since it was their error, not that I was even informed of the call out fee, then they call me numerous times regarding their call fee cause clearly they don’t log communication with the client. They then debit my account without authorisation of the R600!!!!
