RMB service suite useless

In November 2020, I could no longer make payments to my credit card account, not via inter account transfer, nor from any of my other bank accounts.

I started emailing them asking them to look at the issue, and was just ignored. From there on I tried calling them on a monthly basis with no help whatsoever, no consultant is able to help me, as I need to speak to another department. When they transfer me, I get cutoff around 50-80 mins of waiting on the line.

Fast forward to the 5th, I notice the account is now in a "legal" status, naturally, I call them again and send numerous emails. I eventually, for the first time, receive a call from one of their consultants. He advises me that he is going to wait with me on the line to their legal department. After 40mins of waiting, he tells me their lines are "broken", and he will call me back.

Another 2 weeks have passed, 3 emails sent, 4 attempted phone calls. No assistance. No help.

Why in the hell is it so difficult to pay YOU, why is my account transferred to legal, even though I have tried my best to pay you, with you rejecting the payment?

I am just at the point where I am just going to switch away, there is no point in paying premium fees for private banking, when they just ignore you.
