Welcome to FlyerTalk @Feran and especially to the BA branch. It sounds like you had a bit of an unpleasant experience and met an agent who might need a little help with her people skills. Thank you for sharing and please do keep us informed if you receive any response to your complaint.
I must admit I wouldn't have been too concerned in the circumstances you report, at least as far as the bag is concerned. The bag and its owner will have been screened at security along with everyone else.
I hope your experience has spoiled your trip. Please do stay around, it is always nice to see new contributors.
