Just had a right BS exchange with PayPal.
I bought a TV ~1300 on 3 years 0%
I then bought a shower for ~£480 on 3 months 0%.
I then decided a £480 shower was dumb AF so cancelled it. PayPal have then credited the £480 against the £1300. I hadn't paid much attention as the reduced term/payment on the TV didn't bother me (I think it was £48/mo vs. £26). I thought I'd query it though yesterday, as when I clicked it only showed ~£800 outstanding.
Turns out they applied the £480 refund to the £1300 deal, and the £480 for the shower I don't even have, is due 22/05. WTF?
I said fix it and they said "they'll try", with no ETA.
Love to see PayPal hasn't changed a bit since the early noughties!
