Poor service

I opened a credit card, which was approved and went to the branch to get the card as per our discussion, when I get to the branch I had a problem with my fingerprints which they took my id and sent it to HQ for them to bypass, since then I have not get any reply from them when I call call centre they send from pillar to post and when I call the branch they are waiting for the manager whose always at the meeting, where can I complain?
