well..a few word of advice.

If you are going to buy handphone from these shops and especially kiosk booth, make absolutely sure you check the phone completely. If you have no time then better don't.

Another mistake you have done is paying first before checking the phone. You must insist on checking the phone and testing everything before paying. If they refuse then just go to another shop. There are no reason to buy from these kind of suspicious shops. If you think...this shop selling cheapest...I don't wanna lose the deal. Well...it's too cheap to be true.

Last piece of advice is you can only go report them in Consumer Association and Tribunal Court.

Google for consumer association malaysia and tribunal court malaysia.

Goodluck.
