Lashed out

I went to placecol wonderboom around 11 on Saturday to try and get my eyelashes done and I was told they are fully booked I asked if there was space for tomorrow they said no but there is space on Monday being today at 10 I accepted although it was far I moved all my appointments so that I can make it. Around 10 I saw I was still far I called them to inform them I will be late and they said OK. Only to receive a call 15min later when I was already at the malls gate that I could not be assisted I tried to explain it to the lady that this is the only time I had and I. was already at the gate and she told me she had a client already a d will only finish at 3 abd thereafter she has another client. Is it only one lash technician in that store as I had spent my money to get to the mall and ensured that I called to inform them
