Standard Chartered Bank — over-limit charges

Address:

The over-limit charges are to be charged only when the purchase has crossed the limit. The purchases were within the limit but due to interest and other charges the total outstanding becomes more than the limit. Please note the purchase was within a limit only, why the over-limit charges will be added just because of additional charges.
The over-limit charges are to be added once in a bill but i have seen, they have charged twice in a single bill as over-limit charges.
Really unsatisfied with standard chartered credit card. The worst card ever have seen. I also use other cards but they are quite supportive.
Scb credit card is the worst.
