Unfortunately by reading the email address of
titttiez@yahoo.com I have reasonable doubt that this Farlack is a bought account just like user tittiez here
https://bitcointalk.org/index.php?action=profile;u=51152 and I think they are under the same hand which is using them to scam people.
Now this is becoming disturbing.
What a user can do to safeguard himself is to check post history of the user he is dealing with, it will help you in a better judgment. For example user tittiez comes back after 2 years of inactivity and immediately scam a user for 258 USD in Neteller here :
https://bitcointalk.org/index.php?topic=1615084.0I think both accounts are connected or the same user is using them and the email address used is enough evidence for me.
Sorry for your loss.
Dispute is easy, I don't remember now as I am not using Paypal since a long time.
Just google how to dispute a paypal transaction and you should be good to go.
