Quidco payment for declined mobile phone.

polomints

I just had a Quidco payment go through for a phone I was declined in April, back then I tried to get a phone and it did not arrive as I failed a credit check, I can see quite a few failed cash-back attempts from when I tried to get a phone earlier this year, however, I just had £37.50 "confirmed" payment from the Carphone warehouse.
This seems to be from my initial attempt in April.
This is obviously a mistake and I checked my bank, I've not been charged for anything, so I'm guessing this is just some kind of mistake, should I just see this as free money and run with it?
