Does anyone know who I could report a GDPR breach to please? For months I have been getting random catalogues through the post most days from companies I have never heard of and certainly never shopped at. Recently I'd had enough and decided to contact these companies to ask them to take me off their mailing lists and to ask where they have got my details from. Many of them have come back to me naming a particular data company. I am really cross and have contacted them about the breach of my data and they sent a generic response. I have also emailed the Information Commissioners office but haven't had any kind of response from them even saying they have received the email. Today I have received two more random catalogues through the post, it is never ending!! how do I stop this and complain please as I feel so cross and upset my details have been passed on like this. Surely it must be illegal?! Thank you.
