Standard Bank Vehicle & Asset Finance has failed me.

I am extremely disappointed with the service I received at Standard Bank.My credit profile has been adversely affected because of an internal issue they had with their debit order system.I logged a complaint with their complaints department which took them over 2 weeks to acknowledge.I got an sms on the 24th of January 2022 advising that the complaint has been resolved and I will be contacted with the details,but I haven't been contacted and yet my complaint is resolved.I didn't expect to get such a terrible experience from such a big organization.
