It sounds like the prong in the middle of the AC input is loose and therefore not making a good connection with the charger. What do you mean when you say "it won't come all the way back on?"

Out of synch as they dont work or lag? If they lag shut your phone off and reset it, if you have done that plug it in and see if there is new software to update it with, if not it might actually be an internal issue!

turn off your phone. then remove the battery for 5 minutes. also make sure your charger is not plugged in. then put the battery pack into the phone. it should clear up. also you might have over charged the battery. another solution is to buy a new battery pack and if that does not work your phone is acting up on battery basis

Be very wary of that sort of thing - particularly as you are calling an unknown number and - perhaps they want you to put in some numbers according to their instructions to 'have your phone opted out' - I'd risk the marketing people myself - I have such fun winding them up with various stories.
