My mom is on disability. She is concerned because she hasn't got hers yet either. She got the last one very quickly, but her friend who is also disabled got her weeks later. I don't know what causes the delay, but sometimes it's weird like that. I wouldn't stress it too much just yet -- it'll get there! hopefully!

I have to wait for mine to actually be physically mailed so I may be playing the waiting game a while hahaa
