Poor communication and lack of assistance!!!

I have attempted to make contact several times and noone responds to me via what'sapp or the online request forms..

I booked a flight with British Airways... My account was debited with R3100 for another airline that I had no clue off...

When checking app it's shows I have two flights booked with two different airlines for the very same day...

I need someone to please urgently assist me in getting this resolved... I don't even know whom I'm actually fyling with... The chat agent just ignores all my msgs the entire morning, I'm very unhappy and disappointed in this poor service and poor communication platforms by Travel start... I need and want answers today please!!!!!
