Want to ask, my sis apply m2cards recently. She has no Maybank acc, how can she change the credit card pin? Call to call centre, was told can only do it at branch OTC or via m2u... n she receive temp pin via sms.. when try to register m2u acc using credit card number + temp pin, it shown transaction declined, anyone know what is the alternative way to set credit card pin beside going to branch?

that's why

i find it weird why declined. that petron accept amex too(my regular station)
