Today i create a account on Betfury and deposit $40 with 120% bonus and then they ask for 40x wagering. even this is a huge wagering requirement I start playing Dice but when i see they count only 20% of my bet amount as wagering. when i bet $1 wager add 0.2$ when i bet $10 then wager add $2. i was surprised when i seen this and i immediately contact support and they told me for orginal game wagering is 20% for bonus money. it means if i accept deposit bonus then i have to complete 200x wagering for unlock my bonus. it is totally trap coz 200x wagering is totally impossible to do. if someone accept deposit bonus then he/she will not able to withdraw there money anymore
Read the term before you join it, that's key before joining any platform or any contest, promotion program.
You only can say they play badly with you and other users if they don't write it in their program terms. In fact, they wrote it down clearly and the rest is up to you for reading it carefully. It can be a trap, if you see it, but you won't be trapped if you read terms carefully.
Lastly if you feel it is unfair, you can simply don't try to claim the deposit bonus, but bet normally and you can withdraw you money after minimal wager requirement too.
