Vodacom is charging me for iTunes I don't have

Vodacom is charging me monthly on my contact for iTunes I don't not have. Every month since I took this contract from 2019 I'm being charged so much for iTunes. I don't even have a Apple device. I've been complaining about this to them and nothing is done. Even yesterday I went to the vodacom store in hyde park corner where I signed my contract still NOTHING instead I'm told to inquire at Vodaworld. I've been to the Apple store in Sandton and they told me I don't have a Apple account. I have a Samsung and never used ITunes, my contact monthly bill is so high!
