For girl #1 you should have told her you weren't interested unless she wanted to make it up to you. Make it playful and teasing but deliver the message: You're not waiting around. Stop texting her after you deliver the line "Hmmm, you'll have to make it up to me. Second time you've flaked on me babe and my schedule is filling up with other offers already. Tick tock.

"
After this give it a day and if she messages you and thinks you're ignoring her just say you were busy with college work when you get around to texting her the next day. Don't go too far and say you were meeting an "old friend" unless you have a lot of rapport with her.
For #2 just take it easy and be willing to ditch her. Have fun with her, be careless and tell her she's going out with you for drinks that night. If she makes up an excuse just forget about her.
Honestly, if you're playing women to the point that you've got their numbers and got them on fb you're doing something right but there's a lot in to the PUA scene that i've learned you just need to know. You could have come on too strong for a sliver of a second a month back and they'll remember it and act around that by not taking you seriously or not being around you.
Also, what the fuck dude. You've known one of them for two months and not sealed the deal yet? Have you even kissed one of them yet or just flirted with them? A month is a long time to drag this thing out. If you're really getting anywhere you want to get some sort of closure within a decent time frame, not allow it to be strung along for months on end 'cause you will be zoned.
