Refinitiv is a global provider of financial market data and infrastructure. LSEG (which absorbed Refinitiv) says to exercise access/erasure/objection rights you should 'visit this site' via a link in the privacy statement, but the underlying rights-request URL is not stated in the text; the only concrete contact given is the Privacy Office at privacy.enquiries@lseg.com (or postal addresses in London/Frankfurt/Dublin). Note that the World-Check screening database and Enhanced Due Diligence products are covered by separate privacy statements, so a request here may not cover those records. The statement says they will ask you to verify your identity 'if we need to' and gives no fixed response deadline.
