I have not use both of the sites you mentioned.
However, if you want to start a scam accusation against anyone or anything, bring some proof with you.
You can say they have bad odds, give me proven statistics of their ridiculous odds? For example give some odds from wizard of odds?
Just because you bought a watermelon from a supermarket which turns out to be rotting inside, you cannot accuse the supermarket of scamming you or selling all rotten watermelons can you? If you want to argue for a refund, you need to at least bring said watermelon back don't you? Similarly, you are listing all their bad points without giving some examples? Like the so called promos? Link some with the fine print you mention.
There are always companies that are unscrupulous and everyone knows about, but even if you want to take action against them, you need actual proof, not random accusations with no examples
Another one is the countless tech errors . If anyone has played this site, you will have many errors they have too look info.
Like?
In the past a support person name andrea has helped whenever there was probs. Now there is not good support people and they are part of the problem
So if they brought back this andrea for you personally you would say something else?
Your scam accusation is looking more like speculation rather than an actual accusation with proofs.
