Private Banking pathetic service

I reported problems with my credit card to my private banker more than 2 days ago. It has still not been resolved despite me sending over 3 additional mails including confirming the validity of a transaction that they queried. My card has now been rejcted multiple times which equals multiple times I have been embarrassed. Then is frustration II thought I would phone the card division myself. Afterwaiting over 5 minutes for someone to answer I eventually had someone answer to have to go through another 4 minutes of questions before I couldn't answer a question on how much my overdraft limit is. So back to square one. Still no card and no private banker who is assisting me.
