As subjected.

I received the applied stand chart card and was using it for the first transaction at Shell petrol station.
i pumped rm70 bucks worth of petrol. 2 hours later, i received a sms notification on my phone telling me that a rm200 transaction has been charged to my card. the petrol kiosk was the only place i have used the card today, this month, ever since i've gotten my card.

i call the bank's call center, the call center staff told me the system is down, he is not from the call center department hence he cant advise much.
but according to his personal experience, this is perfectly normal and attempted to get my details (including name, phone number, ic, AND credit card number), which i refrain from giving the later. he also told me that there is nothing the bank can do about the charges and i should contact the merchant ( the petrol station or the petrol company) instead!

i called the bank 7 hours later and confirm that the system is up. the second call center told me the same,
(1) she cant do anything about the charges
(2) this is taken as rm200 deposit and the balance would be credited back to the card in 3-5 days time
(3) i shouldnt and i cant lodge a complaint because it is not the bank's fault.
(4) this is the normal/standard operating procedure and i SHOULDNT lodge a complaint.
(5) EVERYTIME i go to petrol kiosk and use my credit card to pump petrol, rm200 would be charge to my card first and balance to be credited back later.

do all standard charted credit card user / bankers out there, is this really the normal procedure?
i cant believe how 'freely' a petrol kiosk can charge to my card. what if they someday happily slap me a 10,000 bill? should i just cut the card?
i dont have the same problem with other credit cards of mine. help!
