Bad customer service

I have app**** for a credit card and submitted everything that was required. Till today I have a card which has not been activated. It been a week now. I was told to go to the branch and I had to skip work to go there yesterday. Even now the card is not been activated. What should I do. When I call the call centre (Activation dept) I was told it will b done. But nothing has been done since last week Wednesday.
