The refill bugs are a nightmare
First package which was 200 baht and bought at 7 11....refilled 200 baht to buy the second month but before I could get to the menu the credits showed 199. So I had to go for a 150 baht package which was way slower to be honest unusable. 7 days later I went to the dtac store in samyan to make a complaint and they couldn't find the reason....my refill balance of 49 was by then only 7 bath. The got me a refund so I could get the same package again which I had to to straight away as the refill status changes by itself. And just now I needed 90 for my last 8 days so I buy 50 and 20 and....the app tells me you'll have to wait for a bit. Guess what the refill is getting less and less which makes no sense and technically is also not possible as my phone has wifi and I have no active subscription now. All above there is NO support in the app. Worst company. Don't buy through the app, only new card at 7 11.
