Well Curve have really annoyed me with their latest change to refunds.
Now refunds go into the "Curve Cash" account, so that you're not waiting for processing time to receive it back into your bank. I like the idea in concept, but they've implemented it before they've worked out a way to give an option to recover it back to your bank.
I've been waiting on a refund for about 3 weeks and have kept checking my bank and hassling the retailer about it only to find it's been sat in my Curve Cash for ages with no ability to receive it back into my bank. They "hope" to have something in place by the end of the month, but it's disappointing they've not held off until they had something workable. It's not like it was a feature that couldn't wait. Luckily it's not a huge amount for me, but imagine people waiting on refunds that they needed for living expenses etc.
It'd also be interesting to know how much they earn by kindly holding all that refund cash.
