WORSE BANK EVER!!!!

After changing my bank account to standard bank due to fnb poor service and endless problems with money being deduct from my acc for no reason! The manager of fnb cape town told me to use my fnb cheque acc details for my loan debit order instead of my loan account. I get a call from a debt collector saying my account in arrears. I go to the branch and show them proof the amount went off for the loan and am told it went to the cheque acc not the loan acc bt the manager!!!! Told me its okay. The money is not in my cheque acc and it has not being credited to me so whr did it go? After posting on hello peter the first time fnb apparently tried to call me but received no calls. The matter has still not being resolved but they have the audacity to double deduct the loan amount which was paid already!!!! What kind of service is this. Ill be damned if I get blacklisted due to *********** staff and will not leave this until its sorted!
