Google *******ly Debitting Bank Account

I was paying for youtube premium through google. all of a sudden i am being charged R350.00 for storage on gmail, which I do not need and there is no package even near to that pricing. it is 3 weeks later and after sending proof after proof for 3 weeks in a row now, I still have no refund and I still have no outcome, so google is *******ly taking money off my account for a service I did not buy or subscribe too, and my google clearly shows only the Youtube Premium as a purchased subscription.
