Vodacom

I bought Alcatel tablet on contract early this year with Vodacom, the contract I bought it was R 99 pm, monthly package of 2G day and 2G at night, during the lockdown Vodacom May 2020 they deducted R 764.16, June 332.10, July R 270, Aug R270.00 for the contract, and now contract has increased from R 99 pm to R 270 pm, I do not know why,

can Vodacom please rectify the contract as was advised for R 99 pm and refund extra money that they deducted from my account caz the contract is R 99 pm not more than that ( call me on this number ***)
