Very poor online service from Standard Bank

Understandably during the Covid-19 pandemic, there are less staff available to answer phones but it is simply unacceptable to provide customers with email addresses (to avoid customers the frustration of holding on the phone lines for very long periods of time) which bounce back. The email address provided by Standard Bank for my query was "***" My email to this address bounced back. I then tried the online "we will call you back" option to which I received an sms response almost two days later asking me if I had "transacted" with the bank and for more details on my query. Standard Bank needs to explain why they are providing incorrect email addresses to clients and why their call back option is taking so long to process. I eventually had to take a day's leave from work to go physically into my nearest Standard Bank branch to sort out my issues. Surely, with the current pandemic, Standard Bank would rather encourage customers not to do this but rather they would make extra efforts to sort out all queries, wherever possible, via phone or online?
