I recently made a deposit to Efbet to check out the offerings and to enjoy some of the nice odds I found.
The site is overall below average, but I did win some money and decided to withdraw after a good month of playing. I deposited using Skrill and did not realize they charge a 3% withdrawal fee (NO CAP, absolutely ridiculous). I tried to arrange a bank account withdrawal, but no other withdrawal options were given to me.
So since there was no cap on the fee I paid quite a hefty sum that the support were in no way willing to discuss. All I got as a response was a referral to the terms and services in broken English.
I would avoid this site in the future and recommend everybody to do the same. I also think the SBR rating of C is much to generous for a site with a huge withdrawal fee forced upon the customer.
