So i have a your plan account with currys with a £300 limit. I purchased a monitor (£159) that 6 months later ended up having a power fault. I then returned the item to currys to which i got a refund to my credit account. I had already paid off the monitor including 29.9% interest (£206 total) creation finance, the holder off the credit account, told me they can only refund me the £159 and not the interest so i am £47 down. Anyone know if they are allowed to keep the interest after full refund?
