I did have a cash advance last month, but that was (I thought) paid off in full including interest charges and fees that will make me much more careful about bringing my debit card with me when I go shopping in the future. Once before I got an interest charge reversed in the current situation.
Retailer charges me twice for the same thing. Phone card company to complain, am told that the duplicate charge will be made good with a credit. In one month, card company takes direct debit for amount owed minus the duplicate charge. Next month credit is made for the duplicate charge. Interest charged on duplicate charge for the original month.
The interest, in that case, was refunded immediately with an apology when I phoned to ask what had happened.
It could be the £30 I took out for spending before christmas, but I was assuming that all charges and costs relating to that would have been in the bill I received at the end of December. Certainly there were costs and charges there.
Cheers,
