It could be, but even if it is, it’s clear they are complaining about fraud in the weirdest way possible.
1. They’ve been a victim of fraud because they transferred money to someone who has a Monzo account.
2. They’ve complained to Monzo and not their own bank.
3. Of course Monzo aren’t able to refund them, the complainant isn’t their customer.
I have never, ever heard of any bank refunding someone who isn’t their customer in such circumstance.
Slight misreading of original. Still a weird focus of complaint, though. The fact that the alleged fraudster uses Monzo is irrelevant, and bank transfers are always done at own risk.
So either the original twitter is an idiot who doesn’t know how banks work, or they’re a bad actor who is deliberately manipulating the situation to make Monzo look bad through no fault of their own.
