If I got 100 satoshi when I read every complaint for this wallet I would probably have already collected 1 BTC

Joke aside, even though I have an account on that service for years and have never had a problem (not the slightest), I personally wouldn’t keep more than $100 there anywhere I don’t have complete control over my private keys. Of course, I say this from the position of someone who does not trade, and one should understand those who cannot avoid that risk.
However, I can't completely dismiss the suspicion that something is really wrong with this service, especially when it comes to 2FA - given that most complaints are due to this feature. I also use 2FA (e-mail), but it is unique and with a very strong password, and all login data is always offline - I don't see how anyone can get hold of it except to infect my computer with a keylogger or to click on a phishing link, and is really unlikely for both.
I can’t say people’s claims aren’t true, but I also can’t say it’s not user error - so as long as my account is secure, I won’t say that service is scam, but there are so many better ways to store your crypto and avoid such a risk.
