Anyway, you should send in hate mail so they'll cut Jim's service.
Seriously though, try to find a phone number, call them up, tell them you do not have their phone and all that. Then again, since you don't know stuff about this person, they might just go "Stop lying, bitch." In that case, block their email or whatever. Really wish you could send stuff back up to them and cause them problems for their own stupidity.
