Vodacom How disappointing

my husband and I have been clients of Vodacom for nearly 13 years- 2 years ago we took out a contract and signed a 24 month contract. we have now been handed over as they say its a 24 month contract but at corp Connect it stated a 24 month contract- I have now been given over to lawyers and I keep getting called and I keep telling them the same thing over and over- I have been in contact with corp connect as well where they have submitted a from for the dates to be changed, since April 2023 I have yet to get any feedback. but the lawyers keep phoning. Im not being funny but im paying my second contract every month and they have now blocked the sim card so this means im paying for data that i dont get. Im really disappointed with this whole situation as Vodacom has not phoned me once!!!!!
