*****ulent Contract account - poor service im getting

I have no affiliation with Vodacom whatsoever. Last month on the 21 April 2023 an amount was debited off my account! I went to one of your branches and lodged a query. Was told to bring a lot of documents (bank statements, ID copy, signatures). Was advised it was sent to the ***** department and that someone would call me. Today I wake up to an even bigger debit order, still no call to update me and when I called in, I was advised it’s still “in progress”. I’m trying to understand why is this taking so long and how long must I wait ?? I didn’t apply for anything and for me to be told I must wait while money is being taken from me is truly beyond me!! Can someone resolve this ASAP!!!!!
