First, it is possible that you have encountered a scam text message, but you can ignore it (basically what you have encountered is a scam text message)
Second, if you are sure that the message you received is genuine (sent from 95599, contact number 95599), you can contact customer service for verification
Third, even if you apply for a credit card, if you have not done the automatic deduction association (it must be done at the counter or through U-shield online banking) It will not be automatically charged to your card
