I see not much ppl able to get the GST waived.

But a month before the anniversary, I called them and request for cancellation. A week later they called me back asking me the reasons, and I said I do not want to pay for the GST. Then immediate he tried to retain me by saying that RM50 will be debited into my account within a month.
Well, I did get the RM50 debited into my credit card!
Btw, I only used this card only once in this year!

No.
