Completely my mistake but I did not realise that purchasing some foreign currency from TUI and using my Tesco credit card would incur a cash transaction fee and interest.
I am someone who has their full statement balance paid off every month automatically by direct debit. Statement generates on 12th of the month and is paid by DD on the 1st of the following month. Never ever ever get charged interest so have no idea how this works.
I now understand I’ve paid a one off transaction fee and will be charged interest on the currency transaction from the date of the transaction (14/11). With my statement not due to be generated until 12/12, that will be a month’s interest. If I pay the statement balance off on the 13/12, will the interest then stop accruing?
If I pay my current whole balance off in full to take my card to £0 tomorrow, would that stop the interest? Or do I have to wait until a statement is generated?
Incredibly annoyed I’ve managed to screw this up - the money I saved myself going through TUI I’ve now more than lost in transaction fees and interest.
