Capitec doesn't care about their customers

my account was debited R95.99*20 which is R1919.8 in total, without my concern by microsoft Za and i went to the bank to reverse the money. what shock me was that Capitec wanted to charge me R80 from each R95.99 meaning they will take R1600 out R1919.8 that i lost, then i contacted microsoft Za they rep**** me with and email stating that i should contact my bank to reverse because they can't do it from their side and capitec doesn't wanna reduce their ridiculous charges.
