I had my sight test done at Boots Tottenham Court Road. When I asked for a further copy of my prescription they refused citing 'data protection' even though as I explained, this was my personal data and I was requesting it. The opticians manager finally agreed to email it to me and hung up the phone. He never emailed it to me. In the questions they asked me it was clear that they have a policy of doing this to prevent you from buying frames elsewhere. In any event, they were incredibly rude and I felt very let down by their poor service
