My order was not done accordingly

Firstly i cant get through on the number i got on the internet ***). So i went to the store to order my take away breakfast. I stood in front of the cashier for 10 min while 3 staff members were standing there not even acknowledging that i was trying to order. Eventually someone asked me if i would like to order. I did but this lady could not help me because of some system issue. Then she asked Ntombi to take my order, she first complained to her colleague that she has 2 many orders for the promotion. Then agreed to take my order. Without writing anything down. I was very specific about my order asking for brown bread and scrambled eggs. She went to place the order and after another 15-20 min, she came back with my order. I paid and left. When i got back to work i opened my meal and it had nothing i asked for. The eggs were done as per normal and i got white toast instead of the brown i asked for. Ive been trying to call back to complain about this but the number is always engaged.
