Standard Bank disappoints again

I've trying to get a new card sent to me in Taiwan but the service has been far from stellar. Basically phoned call center and was transferred around so I ended the call because it was so expensive. I emailed my prestige banker who was out of town, so I forwarded my email to the email address advised. One response asking for some details, I responded and haven't heard from them since. Used their chat function in the app and first operator, Grace, sent me messages then just canceled the chat for no reason. So I started another chat and the operator advised he couldn't help and would send a notification to my prestige banker to call me. I'm still waiting for that call. Standard Bank, how do you operate like this? Get your act together please and get my problem sorted
