I emailed a charity about concerns I had regarding one of their fundraisers. They rang me and assauged my concerns. Said fundraiser has now contacted me directly regarding this complaint - they've done it on social media. Personally I don't have a big issue with them knowing I complained because their behaviour was questionable to say the least, but I am uncomfortable about them now potentially having my email address and phone number.
The fundraiser has seen the email I sent. If it was forwarded to them, they will now have my contact details - and I am very uncomfortable about that.
I think morally if someone complains about you, you have the right to know who did it, but at the same time if it's a member of the public what are your rights regards GDPR?
