NEED HELP reguarding welfare emergency

Cara • Baby boy due May 30th, 2017!
I got accepted for emergency SNAP benefits. Just recieved the packet in the mail. It says I have 155$ in my EBT ACCESS account, but I do not have an EBT card. I do however have a yellow medicaid access card! Not sure if they are connected, or if I can use that. Should I be revieving my EBT card by mail in the next day or 2? Or should I have already recieved it? I called 5 times and it keeps telling me there is no one available, probably because it is a holiday. What should I do? Someone please help!
