Somehow Natwest have mixed up my details, with those of another customer, and I've received messages this week providing information I definitely shouldn't have. I contacted them to make them aware of this and the advisor I spoke to seemed very shocked and said someone would get back to me the same day. It's now been 3 days and they seem to be very reluctant to tell me what's happened, and what, if any, of my information has been breached. I've tried using their online chat facility to find out what's happening and have got some pretty abrupt and what I would consider unprofessional responses. AIBU in thinking a breach of data protection should be taken more seriously?
