Bad service

Recommend not to fly with British Airways.... Reason being firstly - me my husband and small child flew with BA on the 29th if dec booked and paid with BA went to check in so the lady at checkin was rude after I asked would my bags be opened she said NO... So we proceeded the next morning I started unpacking as we got home late as we stay +-60km away from or tambo i had come across that my baggage was indeed opened and BA employees felt it was appropriate to go through my luggage and ***** 2 of my treasured perfume worth alot more to me than thier expence.. So secondly i proceeded to contact BA but they were stil closed for the festive season so found an email address to send a complaint so i sent what i had discovered... They responded and said i must send proof of purchase these were GIFTS hens it was CHRISTMAS.... So i explained this to the operator that was in communication with me so they asked for my bank acc details i sent them tge reply i received AFTER sending my banking details was that unfortunately they cannot help me any further i should come in contact with comair so my issue being i booked and paid BA i feel fiolated and disgusted in the BA treats these types of cases.... Rather fly with a different air service while traveling.....
