This must be a common scenario.
A relative gave me a Christmas present of an outfit. It is the complete opposite of anything I would ever wear. It was far too expensive to shrug off as 'one of those things' and shove it in the wardrobe never to see the light of day.
There are plenty of things from the same retailer I like and would wear. It was purchased online. So I contacted them and asked if I could exchange it.
No problem, they said. However, they will need to email the person who bought me it and tell them I'm exchanging it.
Which I really can't do - they will be really offended because they thought it was gorgeous and the very last thing I want to do is upset them 
I asked why and was told its an automated email which goes to them. I pressed further and was told it was a shipping email and they can't stop it. They said they 'have to' tell the gift-giver because they are the original purchaser and this exchange would be 'activity on their account' and under 'GDPR law' they have to tell them.
I asked if I could just do a straight swap of it in the shop (rather than return it via online), they said no because it was purchased online, only things purchased in the shop can be exchanged in store. I said if there is no receipt, how would they know where it's purchased? They said they can only do it in a shop with a receipt. (this also seems weird)
Surely this is not right that they "have to" tell for an exchange? If I wanted a cash refund then fair enough, but I just want to swap them. If the purchase was made in-store then they wouldn't be able to contact my relative (unless they made them give their email at the till, I guess), so that argument that they 'have to due to GDPR' doesn't make sense to me, as surely it would apply regardless of where it's purchased (and I haven't heard it does?)? I also explained that I don't want my information shared with my relative in this shipping email and I don't give my consent for this, but they weren't interested 
Are gift vouchers in exchange, or a quiet swap of presents no longer allowed?
I can't sell it, as I don't think anyone else would wear it either. It's for a very niche taste.
I think the GDPR thing is a fob-off, but I am at an impasse as they are saying they can't do any exchange without notifying relative.
Please, can anyone help me?
