Sub-standard service from Standard Bank

Apart from a "copy-paste" response to my earlier post regarding the blocking on my a/c due to a simcard change on my new phone nothing was done to enable me to access my a/c, so I waited for 24 hrs, logged in and got the same ***** alert message. I contacted the ***** centre and was told I need to go to a bank branch to resolve this - a totally different "solution" to the previous day! After insisting on escalation to a team leader and being asked if I still had my old phone (!) I was put on hold and after 20 mins, I cut the call. The team leader later called me back and after answering a whole ream of security verification questions ( and being asked which branch held my a/c - was Alberton but this branch closed!) and having to listen to a lecture on how to keep my a/c secure, the a/c was finally unlocked. A totally "SUB-Standard" experience for a 79-year-old long time customer!! What really gets me is that there is no warning anywhere on the Standard Bank system for customers to notify the bank of sim card changes. And just what training does the call centre staff have - two conflicting responses for the same problem? Instead of being asked to stay on the line, why not offer to call back?? Pathetic "service" from a supposedly high profile bank.
