Money Refund

I took out a contract in 2017 with Vodacom at Game store in Cape town, when I took out this contract at that time it was advertise as 2 of the same samsung phones in one contract of which the lady told me I will only pay one instalment every month. (she also explain to me that the primary number which was *** will get the majority of airtime and the secondary sim card number *** will get get the balance of the airtime. after 24 month I did not upgrade and inform that I would like to cancel my contract and want my primary number to be change to prepaid. Recently I got a phone call from vodacom informing me that I'm due for upgrade of which I told the lady I don't have any contracts with vodacom at all and she informed me that every month vodacom deduct R60 from my account. When I check my bank statement I saw that R60 does go off every month from my account. I would like my funds to be paid back into my account from the day I cancelled my contract back in 2019.
