I bought my nasi goreng at my favorites restaurant using MAE Maybank. At the area, my mobile network was not so good. So when I wanted to make payment, I got alert of unsuccessful payment. (Unfortunately I didn’t take the screenshot).
So I tried 4 times and all of them unsuccessful payment. I gave up then I used Touch & Go e-Wallet. I could easily made payment with TNG e-wallet even with bad mobile network. At that time I was wondering whether it was my mobile network problem or MAE problem.
Account Deducted Event if Unsuccessful Payment
After paying my nasi goreng, I went home. While on the way suddenly MAE alerted me that all the payment were successful. To my surprise, my account have been deducted.

I had to rush to the restaurant and informed them I had accidentally paid more than I should. Fortunately the restaurant gave me cash on the extra payment without much question.
4 Chances to Play TAPastic
Indeed MAE deducted more than they should but at same time I got 4 chances to play TAPastic.

Lesson Learnt
If you get unsuccesful payment. Please stop and use other eWallet. I notice MAE eWallet loading time takes longer time than TNG eWallet.
