Truly fed up and may never order by mail again. Have just spent 20 mins from a working day on the phone to them- they called.
They wanted my card number so they could take payment for an item which was out of stock when I placed the order last Thursday. (It didn't say on web it was out of stock anyway- a candle.)
So- I queried if they could confirm who they were ( as they phoned me and wanted all my credit card details.)
Then they told me they never save credit card details for back orders AND NEITHER DOES ANY OTHER COMPANY. Err- sorry what about Boden who takes details months ahead in the preivew?
I mentioned I needed to return the items I ordered last week anyway and how would they refund my £10 gift voucher- I assumed it was going to be applied to the candle, which I was waiting for. Oh no- nothing as simple. She said it had been already applied to the 3 items sent. I told her it had not because the despatch note gave me a total charged to my card and the £10 wasn't deducted. She then told me she'd find out why.....
turns out that the invoice they send with the parcel is not an invoice really and doesn't show what has been taken off your card. 
They say the REAL amount they have taken will (if you use a voucher) be on your credit card statement ( and would I like to check it now- errrr....it only went onto the card 2 days ago.)
So any vouchers you use online do not show against the paperwork they send you with your order.
On top of which their bags are not re-sealable for returns, no sticky address label and of course no free returns.
I don't think I will do mail order again as they are crap at it.
