If after reading FAQs, scanning ToS, we feel unsure, we can chat with support staffs and ask more information we need. Reading and scanning FAQ, ToS by yourself will help you to ask more detailed questions with customer support staffs and they will be able to answer you better too.
If you are depositing huge amount in the casino like me, you should not be lazy on reading the ToS word by word so that you can assure that you are familiarized with rules. It’s not wrong to ask for support help but it’s much better to do it yourself for your money sake.
However, if you are just depositing a couple of bucks then reading the whole ToS word by word is not necessary.
