I am not sure what makes you think that you can start a scam accusation for a speculation for a major mixing website for delaying more than a hour which is unwarranted, you can provide your details before starting this scam accusation, you will get a response from the team soon, have you contacted them through their support system as you will get any response within a day.
People have gotten a lot more sensitive to services not immediately delivering what they promised to deliver, which on one hand is understandable, but on the other hand also not because there is no way to avoid errors.
I personally would wait at least 24 hours before opening up a thread, and then calmly explain the situation as it is. Calling services a scam like this is unjustified and I find it even quite disturbing.
As service you try to do the best you can to serve your users, and then suddenly someone pops up calling it a scam for no reason. That sucks. There is no way you can protect yourself against this....
