Pathetic Service from a "leading bank"

I instructed Standard Bank in April 2020 to close my account. This was during the hard lockdown so I could not get to a branch. I was informed that I had to settle the outstanding amount on mu current account which I did. the consultant informed me that she will close the account as per my request. 2 months later I receive an email from Credit Solution Services informing me that my account is overdue. I called CSS to enquire what is going on, guess what, no answer. I spoke to a Monica at the CT branch who informed me that she will make a note for the consultant dealing with my case to return my call. that was Friday. today is Tuesday, 13:37 on the 7th of July. no contact yet. I spent more than 70 minutes on the phone with Standard Bank today, just to be pushed from pillar to post trying to sort this out. Every consultant I spoke to says that they cannot see any interaction that I had with a different department (note to Std bank, make your customer's lives easier by training your consultants on more than one system). only one, Titus, took the time to actually acknowledge my frustration. one, Nonkululeko actually said "I am giving you advice, take it or leave it". excellent client service by the way Standard Bank. Titus eventually cancelled the products I wanted cancelled in April, I believe that Nonkululeko cancelled the overdraft which I never app**** for in the first place. and still no CSS call. I also logged a complaint on their website, 1 week ago, not even an indication that they received it, and you want to know why I left...
