A month or so ago my DS had trouble with an online retailer after returning two expensive items that didn’t fit - they only refunded him for one. It took weeks to sort out, they were adamant and were requesting proof - photos (does anyone think to take photos of packages they’re dropping off at an inpost locker?) Weight of the box (which he didn’t have because it was a locker) but eventually he got the money back via the bank chargeback.
As a result of that hassle, I ordered footwear I wanted from Amazon rather than other more obvious retailers because I’ve never had issues with Amazon. Spoke too soon! I sent them back as they didn’t fit, using a QR code at the post office. Got the email straight away thanking me for dropping off, refund was issued. Couple of weeks later got email reminding me to send the item back - long story short they claim the box was empty! They then took the money again. It was only due to DS having had issues I actually DID take a photo of the box on the scales, and after several phone calls they’ve actioned a refund.
I’m aghast that they can have a returns system that holds the customer responsible for anything that happens to the item after it’s handed over. Are there warehouses full of dodgy people nicking them? Delivery drivers opening boxes and helping themselves to stuff? I don’t even know what’s the safest way to return things anymore - I deliberately used post office as I assume it’ll all be easy/reliable!
