I received a call from 88639725 and left a message as follows;
"Your phone account will stop service in 2 hours time, please enter 5 to get more information."
Obviously it is a scam. I don't think Starhub will call with such number. This is disturbing for subscribers and wish Starhub can try to trace the number and do something to stop them. You will lose us switching providers if we don't see you taking any action.
