Worst possible service experience for credit card

I app**** on the 22nd September 2015 for a credit card, they approved the card... It is now the 15th of December 2015 and I am still waiting. I call everyday and every day I am given a different story by a new consultant. This company offers the you the opportunity to get credit like a carrot but never gives it, they say it is approved...you send the documents but it is never enough...
