Inability to contact anyone

I like Standard Bank, my family and I have been banking there for years. I do have a rather large issue - it is almost impossible to get hold of the correct department.

I have all the relevant contact numbers, but holding on for 20 - 30 min each time I call is something no human on a cell phone can do. So when my airtime runs out I use the "call me back" feature on your website. I had good fortune using that feature the first time. Every time after that regardless of which department and regardless of which product - NO ONE calls me back.

I have more than one insurance policy and I noticed an unauthorised amount being debited. I really need to speak to someone about that. I already did the "hold on for half an hour" thing and the "call me back" thing this morning and had no luck.

It worries me what will happen the day I need to claim, will there be radio silence on the other end as well?

Please PLEASE could someone contact me? I am not a satisfied customer at this point.
