need assistance from vodacom regarding *****

on 28th of february this year i had realised money was taken out of my account and i found that there had been 31 transactions which i did not agree to, on my bank statement it showed the merchant name vodacom but i do not have any contract or subscriptions with vodacom as i have phoned them and they told me it was *****ulent.The dates of these transactions are ranging from 17 december 2022 till 10 february 2024. The first step i took was to phone the nedbank ***** department and report it as *****, when speaking to the nedbank employee they told me it was *****ulent, they then blocked my card and i was told to fill in a nedbank card dispute form. I filled in the form and emailed it to them on 1st march and they got back to me on 13 march stating in the email "kindly be advised that the transactions in question are out of the chargeback timeframe of 120 days and the cardholder(me) should contact the merchant(vodacom) to have the matter resolved and there is no further recourse so the case will be closed". I would like information from vodacom as to why these transactions have the name vodacom and i was even told i don't have any contract or subscriptions with vodacom i only have a vodacom sim. I need to resolve this issue I am checking both sides with the bank and i also want further information from vodacom because this is a *****ulent transaction.
