Disappointed service!!!

on the 25th May I got an sms that money had been debited on my account to reduce an overdue account, R2700 was taken from my account without my consent and as if I have that much money decorating my account. This has caused me so much inconvenience as I do not have such amount of money on a random month.can I please have my money Bac****!

This R2700 is said to be due on a cheque account which I opened when I was an intern 2013, the account was inactive when I became unemployed. 2015 I opened an access account under the impression that the account is closed, then January 2018 I started receiving statements of the cheque account which seems to have started accumulating interest only then. My problem is what happened to the service fees from 2015 to 2017 of the cheque account when I started accumulating interest only in 2018, when I queried this in clearwater branch the consultant said I must just do my self a favor and pay that amount that is due and not ask about previous years because they might say I owe more.
