Fradulent transaction

I had 3 years tracking device contract with Netstar that lapsed in December 2022. Early in January I had a call from their call centre consultant to discuss renewing the contract, but there was never an agreement, as I indicated my intentions to cancel the month-to-month contract before it kicked in. Then there was deafening silence from Netstar for weeks until a surprise ******* deduction of R 437.96 end on January, which I reversed successfully via my banking app. I then immediately phoned their call centre to cancel everything and I was issued with a reference number for that call (CAS-***), and no one bothered to tell me they have not cancel the debit order. To my surprise, yesterday morning on the 28th of February, the ******* debit order was initiated and successfully deducted R437.96 from my account. I then Phoned their call centre to seek clarity and demand my money back. But I once again came across a very *********** consultant who managed to waste 40min of my time and then hanged up on me, after claiming to re-assign my call to the finance department.
