Telkom at it again. ****** of note!!!

I got a call from a Telkom consultant who advised that i could get the same monthly bundles at a lower rate. I agreed to switch and in Dec 2023 and Jan 2024 they debited the correct amount. In Feb, mar and Apr they decided to deduct 3 times more than what i agreed to pay. I managed to reverse the Mar and Apr debit orders but i could not do the same with the Feb debit order. May i please have my money back as this is daylight *******.
