I've been reading up on the General Data Protection Regulation (GDPR) and I'm trying to understand the specifics around the right to rectification. Can someone explain how this right works in practice? For instance, if a company has inaccurate data about me, what are the typical steps they need to take to correct this information? Also, are there any scenarios where a company can refuse to rectify data when requested? Would really appreciate some clarity on this issue. Thanks!
