Me too kena....had argued with the CS n report lodged 3 times after each time they kept insisted they not wrong and the charges remain valid. after the 3rd report only managed to get the 5 days charges waived but I still have the gst charges not waived....talked to the CS about it and he sounds like blur can't understand what I talking about....finally, I gave up...that gst just treat it as my gift to govt

just checked my bills...oh yes...the international roaming charges are no gst charges....

all the while the I saw my itemized billing the gst charges got shown amount for usage/call charges with an amount. only need me to go break down what are the call Charles being charged only see those roaming call charges are without gst.
