Over the years, QVC have become a law unto themselves. And as for their technical department who do the website, well ....... kindergarten skills spring to mind although a four year old could probably do a better job.
Well I had to a to do with a pair of jeans a while back. I ordered them in black and blow me but they actually fitted nicely. Then I ordered a second pair in dark indigo. When they arrived I didn't check them over as such I just chucked them in my case as I was going away. Went to put them on and they were very dark indigo. So dark that I wasn't 100% sure they weren't black. But I needed to wear them. As I'd only packed enough clothes for the two/three days.
Got back and decided they really were black. Phoned to explain and said I know I've worn but in line with the MBG can I change for dark indigo. Yes, she said, we'll send out a new pair and a label for you to return the black as they are technically not what you ordered. New jeans arrived. Label arrived and I sent em back. I got the notification for a refund. Oh well I thought they'll have charged me for the replacement pair they sent out then refunded the wrong colour pair. Well they hadn't. And they still haven't. I'm sure they will work it out but for now I've two pairs of jeans but only paid for one!
I had something a little similar recently, Tinks. I ordered something and the money left my account. When I tried the item a fortnight later it was faulty. I rang CS, they sent out the returns letter and label and the replacement arrived a week later. I wasn't charged for the second one, but it was showing as 'replaced' against the first order in my account. So presumably the second replacement was paid for by the cost of the first order. I didn't ask for a refund though, but I was expecting to be charged twice as they often bork things up.
As you asked for a refund, it'll be worth keeping an eye on your account as it may take a while to be processed. If they don't charge you for the replacement pair then ....... ssshhhhhhh.
