Vodacom the ******!

Vodacom is *****ing from their clients. In November 2021 I took a sim data deal for R299, in December they deducted R1211.05 from my bank account and I thought it includes prorata for November, but then in January 2022 they deducted R1085.84 from my account. on the 2nd February I contacted them to enquire about these charges and the response was there are subscriptions on the sim card and they can cancel and block them. I agreed to the cancellations but my February invoice is R1248.72, how? when they cancelled and blocked the subscriptions on the 2nd of the month, why am I still paying for a full months subscription that is cancelled? Also, why did they give me a sim card without subscription's? I wouldn't have subscribed to anything with the sim card on the router. No one fiddled with the sim card on arrival, we just put it on the sim card.
