Microsft Stole charge me incorrectly not once or twice, but 35 times.

Bought the Xbox Game Pass for PC, it is only supposed to be R15.90 for the first month, which was charge to my account with no problem, but so were the 35 other transactions for R14 that completely depleted my account. The bank tells me I need to cancel my card and order a new one, but there is still no guarantee they can help me get my money back without proof from Microsoft that the transactions will be cancelled, which they refuse to do. I asked for proof 4 times and they kept dodging the question and instead sent an email to me as proof of the support chat I had with them. They have literally depleted my account and have R9 left, no cash to go and see my son on Fathers day now let alone get to work for the apparent next 3-5 days which, according to them, that's how long I have to wait in order for the transactions to be reversed. They said that the R14 is a charge just to make sure the card details are correct...fair enough...but 35 ****ing times??? Are they ****ing stupid? How on earth can they charge a person 35 times. They have literally ****** my money and no one can do anything about it. I see no reason to cancel my card and order a new one because I'm sure the bank can cancel the transactions, but I always seem to get the useless people on the end of the line.
