PCCW - one of my datapoints:
Went in their office to update new credit card details filled in 3 forms.
A few days later (Sunday Morning) SMS comes in saying my bill was outstandding and if I had paid ignore the message. I ignore the message.
Next day - 24 hours later, Monday morning the phone is cut off.
I go to PCCW office to check if the credit card details are correct - staff confirm, and happily report phone will be back on in 15 mins.
30 mins later I return - phone still not on.
I ask why?
PCCW "It's cos you haven't paid your bill" - seems filling in several forms days before was not enough.
Me - "What the fuck do you think I was in here earlier for"
Bill sorted.
Smartone across the street - bye bye PCCW.
