So this means
or do i calculate as 3776.67 + RM 200 = RM 3996.67 x 16% int rate.
CC Interest is charged on a daily basis.
As per your example, from 27 Sept onwards once it is clear you did not fully settle the balance, you get charged interest from the very first transaction date in the statement. Assuming you have no transactions prior to the laptop purchase, all transactions from 22/8/2012 will be charged interest. And this will continue for all new transactions until you have settled the entire balance in the card.
depending on your rate, it will most likely be 18%/365 on the entire balance to date, looking at it daily.
Thus doing a +200 -200 is not going to save you any interest unless you pay down the card on the transaction date itself, i.e. use RM200 on 09/10/2012, pay RM200 on 09/10/2012
it is miscommunication if they insist they cannot do a reversal.
Unless you get a black and white from Dell committing that they will cover ALL interest charges including for all your other transactions, I would file a dispute with the bank as a wrongful charge and make a very big fuss about it via Dell customer service, Facebook etc.
