Vodacom *****ing money

Sometime during lockdown Vodacom took it upon themselves to add a monthly bolt on databundle of around R400 to my contract. I neither requested this nor authorised this. I have phoned Vodacom TWICE now and have been assured that it has been removed, but it is STILL going off as a debit order. I usually stick to either MTN or Cell C and this is the first time (and LAST) that I have been with Vodacom. I am EXTREMELY unhappy that during these financially difficult times that Vodacom is essentially *****ing money from customers.
