Yes. So I went counter intuitive and pressed 1 to listen to the Thai language. I hope they only have one set of voice recording. If I remember correctly, you wanted to check your account balance. Instruction given in Thai to check account balance press *111. However, instruction in English to check the same is to press 1. Regardless, in both languages, press zero is for customer service.
Hi Dana, I pressed 1 just calling from Thailand just to listen to the Thai language. If you want to contact Officer press 0 (zero). If you want to inquire about account balance press: *111
