I recently returned some items to a well-known French clothing company using the pre-paid postage label provided. Unfortunately the courier (Yodel) seem to have lost the parcel and getting my money back from the retailer is proving difficult. They are asking me to email them a copy of my ID so that they can "open a judiciary investigation", which they say is required by French law. AIBU to refuse to do this? Surely sending a copy of my passport/driving licence to a retail company by email goes against data protection/GDPR? Has anyone else had a similar experience or challenged a request like this? I have already sent them my proof of postage showing the items were returned over two weeks ago, which I thought would be sufficient.
