i need help here guys...

i am using maxis postpaid using a sub line from another number.

right, now i am trying to subscribe for Extra Ten.

however, when i typed *100# keyed in 3 for extra values and 3 again for extra ten,

they replied, 'Sorry, you are not eligible for Value Extras. Thank you.'

anyone faced this problem before, i need help to overcome this issue,

phone bill is starting to exceed my budget.

Thanks in advance!
