This evening (20:52) my girlfriend received a call on her mobile from PCCW Netvigator telephone salesperson. Like in most cases when one receive this sort of unsolicited telephone call, she simply told the salesperson on the phone that she does not have time to talk, which was the case this evening, as she was at a friend's house.
Instead of giving up and move on to the next "victim" on their call list, the salesperson calls her back and said, "... I was not calling to give you an offer, but if I was I would not offer it to you.", then hung up.
First of all these sorts of calls are unsolicited and I would consider them to be SPAM calls. I will be writing to OFTA to file a formal complaint of PCCW Netvigator salesperson's attitudes. Of course, PCCW's salespersons are already famous in Hong Kong for having one of the worst customer facing attitudes so that is not too surprising.
I wish OFTA would have an ordinance like the Unsolicited Electronic Messages Ordinance for regular telephone calls.
