Skymiles false advertising?

I singed up for deltas sky miles program since i fly a lot (about 4 times a year). I thought that by singing up i would get free lugage, faster checkin faster bording sky club access better security lines and first class upgrades. I went to the skymiles checkin counter at Miami and wastold that it was only for their "elite" members. I told them that i was an elite sky miles member. They checked some things and said i was only a general member, which doesnt get any benifits other than getting miles for flights, otherwise it is teh same as being a non member. what the hell? so flying 4 or 5 times a year isnt alot? its way the hell more then anyone else i know. how much do you have to do to become "elite" with them. are all airlines like this? i deserve to have more benifits than someone who only flies one or twice a year or not a all? too bad delta doesn't see it this way. I will be doing business with another airline next time and sending them a letter. i will switch to an airline where i will be elite. damn it!
