She blocked me on whatsapp for NO REASON! What happened?

Anonymous
So this girl who I have known for a month now suddenly blocked me on whatsapp yesterday. We met online 2 months ago, I gave her my number and she got in touch with me after almost a month. We got to talking and met over drinks. It was nice and we both enjoyed our time together. After that she's been calling me every now and then to just say hi and see how I am doing. I asked her out on a second date couple of times but due to other plans she requested me to postpone it for some other time. She just called me yesterday and we chatted for few minutes. Reception of her cell was bad so the call got disconnected. I called her back after about half an hour and she was on the other line. So called back again after a couple of hours and she was still on the other line. I dropped in a whatsapp message to her stating 'I called but your phone is busy' which never got delivered to her. I called again today in the evening and she cut my call. I dropped in a message on whatsapp again and that message has not been delivered either. I'm not able to see her status or her display picture. I don't understand what happened here. She called me her side just yesterday and absolutely NOTHING has happened between us (arguments etc.) for her to be behaving this way. She still hasn't deleted me from Facebook though. Any idea what is going on?
