Reviews Summary

Overall, customer sentiment toward Flagstone’s banking platform is largely negative, with repeated mentions of slow account setup, unresponsive customer support, and withdrawal delays. Reviewers highlight inconsistent experiences, particularly noting differences between personal and corporate accounts. While a small number of customers praise individual staff support, most feedback identifies pain points and frustrations, especially around access to funds.

Common themes include delayed responses to emails, complications with onboarding and know-your-customer (KYC) checks, frequent technical issues preventing account login, and unclear or shifting terms and conditions. Customers express concern with difficult withdrawal processes, lack of transparency on product availability, and inadequate or contradictory explanations from customer service. Account closures and funds being inaccessible or delayed add to the dissatisfaction.

Based on reviewer feedback, Flagstone is viewed as an unreliable option in the banking services sector, particularly for its onboarding, withdrawal, and support processes. While isolated positive remarks exist, the majority of accounts describe persistent operational and communication issues which undermine trust in the company’s services.

Fantastic service with the personal account, sluggish service with the corporate account. James Oliver has been outstanding on the personal account, keeping me updated nearly daily while it was being set up. Unfortunately the corporate account has taken weeks to get any progress and no replies to emails. Hoping it will be open soon.

Dont use Flagstone. I opened our account slowly in increments to test the system but they have just closed my account without warning last Wednesday and have held on to our funds and have not returned them . Nor would they follow my re deposit instructions . My monies is stuck in their holding account without me being able to withdraw it and there I'm not receiving interest and its not covered by financial compensation either. Ive called messaged and told them to send my money back but as of Monday it still hasnt arrived ! This is fraudulent

I have been unable to login to my account for 3 days due to "technical issues". Outrageously bad customer service. When I am eventually allowed back on, then I expect I will move elsewhere
