I just skimmed through the first page of his post history and it looks like calling businesses scam is what he does here – 99% of his posts in page 1 are all accusing different sites of being fraudulent.
He has just woke up from almost 4 years of inactivity then directly accused 2 different bookies as scam.
I have no idea what is his main problem, if it is just about login issue, it can be resolved quickly by contacting support.
Login issue may happen because of several reasons, it can be because our own mistake or it can be an error in the system.
Accusing a site as scam just because login issue without trying to contact support first is questionable.
