Vodacom ********* and dishonest price increase

On 17/4/2024 I phoned to cancel my current Vodacom data contract because the price increase without informing me. The lady in cancellations convinced me to renew my contract as they will match the data I received. I received a quotation from Vodacom for a data package of R329 over 24 months. I accepted the quotation. On my very first month of the new contract, the 1st of May Vodacom debited my account with R360. Upon phoning today 6/5/2024 I was informed that their was a price increase on a new contract. I fail to understand how this works, "The contract terms and conditions" point 2 reads as follows "Pricing can only be guaranteed if supp**** on an official Upgrade Quotation and is subject to change and stock availability". I am extremely unhappy and disgust, with this ********* conduct which Vodacom embark on.
