I purchased PostGrid Pro on June 10 and asked for a refund the same day because the Pro version was NO DIFFERENT than the free version. I have not received a response yet. I will be disputing this charge to my credit card company and reporting this to the Better Business Bureau. I would appreciate a prompt refund of my $21 purchase.
