I just called and inquired about my return. They didn't have it in their system yet, I persisted that she look it up and track my bag down as she said it hadn't arrived back yet, while the parcelforce website confirmed that it had been delivered and signed for on 28/1.
Long story short, I just got an email saying they refunded me the amount plus shipping today, should show up on my credit card in a couple days.
Hope everyone else who returned their bag will be refunded soon so we can all be done with this unfortunate sale experience.
