Firstly, remember that you may be breaking laws in your country by trying to continue using Betfair
The only way to achieve continued use of Betfair is to set up a VPS in a datacentre located preferably in UK. You will need a new account which must have a different name from your old account. This probably means you will need to find a family member/friend who resides in another country where Betfair is allowed. This person should have no interest in using Betfair and needs to open a new bank account and give you control over it. Of course, this person must also be prepared to provide ID documents for the KYC checks when requested - these are usually a copy of passport or driving licence and a utility bill.
If the above sounds difficult or impossible, then I'm afraid you may need to forget about Betfair until European law is changed to outlaw such protectionism.
