Never used a VPN before as I am always afraid that I will get myself banned on some websites

. But that could indeed be a solution to overcome the restrictions.
Can you recommend a free VPN, easy in use ?
Gambling sites usually are very strict with VPN. Not all of them ban accounts that use VPN but if you don't check their Terms of condition or FAQ, you should not use VPN.
When your account was banned because of suspicious log in or VPN usage, and if those activities are considered as ToS violations, your account will get troubles and support won't help you to lift up account restriction. Any sorry words are non sense under the view of casino operators.
