Vodacom lies and deceiving agreements

So my Fibre contract came to an end, November I call on to cancel because initially I wanted to move away from this *** service provider but because they had an offer od R99 for the next 6 months I opted to take the offer as I would be able to safe some cash. THE AGREEMENT is R99 for the next 6 months and then normal billing g of R920 would resume, this supposedly starting from December 2024. Normal amount debited as expected in November and then as of December R99. I get my bill no change fir December, so I log a ticket to make sure yall understand your own agreement, no response since I logged my ticket, so I open a new ticket and I get this response: Vodacom: Vodacom: Service request SR*** update to Closed NoReply(2-14Z15WMH). CLOSED cause that's a indirect F#@$ you we will take your money as we want and F@#$ the agreement we have in place, last call I spoke to an agent who stated they can see that the agreement was not initiated on the accounts department and I was advised they will be informed of this R99 agreement and billing should be fixed but no change because o get this sms: Vodacom: Your next debit order (R2399.00) is on 2024/12/27. If you proceed to debit my account with R2399 I will seek legal help and cancel your *** Fibre contract and believe me soon my two cellphone contracts will come to renewal dates and that too I most definitely will cancel as well, that is no f#$%ing threat it's a promise. Show me you take amounts not agreed to and I will take my minky cat contracts elsewhere, let the fun begin f#$&kers
