British Airway Crew Physically fought with me!!

On Friday the 7th of Aug me and my mother was meant to fly to Johannesburg from Cape Town at 19:00. The flight was meant to be delayed till 23:45 that evening. At only 00:30 be boarded our flight. <br> We returned the following day to Johannesburg Airport to go back to Cape Town on our flight that boards at 17:00. We stood in the boarding line for about 5mins since there was only 2 counters out of about 7 that was open. When we got to the counter to book in the lady told us that we missed the flight by 4min and we can't board anymore. She left me at the counter only to go to a different counter to help someone else. I went to the management counter where I dealt with Zakhele (the manager on duty) who explained to me that we missed our flight and there is nothing he can do. His tone of voice was loud and impatient and talked in a different language to his college while dealing with me. Eventually I removed my phone to take a picture of this guy for reverence. He pointed his finger straight at my face and eventually grabbed the phone straight out of my hands. I immediately try to grab my phone back as he did not want to let go at all. This story continues but my character space ran out.
