Any idea what was the amount of each swipe?

Did you take down the CS's  name. Read back few pages, there was a lady who had a similar case and OCBC was holding her responsible for the charges. Were you asked to submit a dispute form or the CS confirmed they will treat it as fraud?

You want to threaten him with what? Whack him if he don't return you the money and thus you breaking the law? Hand over the evidence to the police and make a copy for your own records and also maybe forward to OCBC.

Here's a thought, next time you talk to the OCBC CS, record the conversation with your phone.

Maybe you should even complain to BNM that you were not notified via SMS which is suppose to have been  implemented as of 1st Jan 2012.

To ALL:
Here is my thoughts on the SMS thingy:

1. The cardholder should be given the option to choose the amount to trigger sms notification.

2. If you see Fraud Call Thread and also recent Link Club Thread, telemarketing products are priced up to RM499. If RM500 is the default amount to trigger SMS notification, then I guess it kind of defeat the purpose as you can see from above case, the card was used numerous times and added up to RM800 without a single sms notification.

2. SMS notification should state amount and merchant and time too. OCBC should do something about this.

3. Bank Negara Malaysia should set precise set of guidelines in respect to the SMS Notification for all banks to adopt and so that the public is aware, else this SMS thingy is a joke.

When I used my UOB card yesterday, not only did I get a SMS notification but I actually got a call from UOB to verify the transaction since I hardly use my UOB.

You work fast. Yah, nowadays the cashiers hardly check the signature.

Any outcome from the hypermarket?

And with you gathering all the evidence, the police don't have much to do except to identify the person and then go nab him/her.
