Overcharge

Today I receive my UOB credit bill and found that Golden Village has overcharge by 2 times. I recall that time is the staff swipe a few times cos the receipt cannot print. So in actual fact, the transaction did went thru and so I was charged additional 2 times. I called up UOB and they told me to approcahed Golden Village first. Very troublesome. So you see, even if your signature is hard to forge also no use. Cos it is useless. As long as swipe, the transaction will go thru.
