unexplianed Charges

on the 25 feb i made deposit of R700 since there was debit order that i know it will take off late even when i made the deposit SMS and my bank account shows me positive amount but two days later i was charge R180 for HonFee, when i call the bank they say those debit take off in the eary hours of the 25th which is incorrect since if it was true i wasnt going to have be able to withdraw more cash. please can someone let me know how you guys do not advise clients? or should i move to other bank
