in the end boost called me today and give me the otp code instead. xox side is pretty useless, they just say they cant do anything. I had never face a telco like this, maybe it just a virtual mobile operator.

so in the future i think i cant simply logout my boost account if not, i have to wait boost to call me and provide me the otp.

for those who cant get otp from boost, kindly make an enquiry through boost email or fb. no need waste ur time to contact xox. they are not willing to help u and blame the issue to others. tq
