I have a question on foreign transaction, i bought an item from UK at 100 pounds on monday, i sign on the transaction using my credit card with the choice of transacting in foreign currency rather than setting direct conversion to MYR on the day itself.

Subsequent to that i return the item(Within the stipulated period), hence a full refund of 100 pound will be refunded to my credit card.

As what i check my statement on monday i have lock on with a expense of RM565, however 3 days upon my return of my item, i got a refund amount of RM550.

Would like to clarified shouldnt the refund amount be net off at RM565? As its the same transacted item/merchant/amount in foreign currency?

Your experience and advice is much appreciated. Thank you.

Yup aware its due to foreign translation different between both days, but shouldn't it be nett off the same, rather than there will be lost or gain at my side if the FOREX rate weaken or strengthen?

If so, i can arbitrage on foreign translation if i refund it at the right time, given our fluctuation of FOREX rate?
