My friend people are unfortunately like that ! Of course not all of the people.....but there are a lot of snatch and run
people. Please don't pay attention to these kind of characters but you have EVERY right to complain. It is not good to
abuse a person's good will and generosity i agree with you ! It is a good idea when such a person does a snatch and run then his/her userid to become public and BAN his/her ass !

Best regards.
