I just got robbed

[a completely inoffensive name]

It is just a cell phone man. You didn't get in a fight and he didn't take much more important things, like your wallet. It was isolated away from your house so he doesn't know where you are and it seem s as if everything will be cleared up with your phone company. Very, very worst case scenario is that you might have to pay for an entirely new phone. I suggest maybe finding a different, probably longer but safer way home? Or keep some sort of personal protection on you, like a small taser. Next time someone starts moving around with your property bring out your aggressive voice and if the next guy pulls the same move at least you won't have been dragged into a side street. Or at least, just be more paranoid and not hand out your cell phone to people. Sucks for any legit people, but that's life. You are lucky he didn't have a friend waiting there to ambush you.

Just mark it as a bad experience and take measures to prevent it next time, no need to worry. I doubt this incident had anything more then the short term consequence of having to deal with annoying cell phone companies. Considering how this could have gone down, this turned out for the better considering you are not harmed in any way and still have your credit cards.

All in all, you should calm down, take the rest of the day off and inform your friends or family about it. They can provide support if you need it.
