No, they told me that my money was there in 7 seconds. About 1 hour later, I went to the ATM, and the money had been added to my balance. This has happened on more than one occasion, so no complaints from me.
A Thai friend of a friend won the 4,000,000-Baht jackpot about 10 years ago. Haven't known any farangs win big money, and my biggest scoop was 4,000 Baht. ????
Probably nothing to do with the box, but the app that you're using. Some contain annoying ads, some don't. Maybe search for a better app/apk. I have the same problem with a couple of mine, but can't find 'no-ads' alternatives at the moment.
