You should not be concerned at the moment about the lack of cards as long as you are getting the programming you want now. If you want to change to the flex pack that is a different story.
This is what I have gone through thus far on cards for the 211k and flex pack. I called to change from at120+ to flex pack. I have 2 211k receivers, neither with a card in them. I own these receivers. They said I needed the G4 card and would send them. Only received one, not sure why I was only sent one, they should have had the information in front of them about both receivers. Called the activation number to ask about the second card, she said the G4 card would not work in my receivers that I needed new receivers for flex pack. She was trying to sell me the service fee so that I could pay for both rental and service fees. I will be playing roulette this afternoon, as I have do not believe this is true. If it is true that I need new receivers, I will buy a couple of wallys.
