Poor service

On the 1st of May I had been to Pedro's at Starwood mall placed a sit in order for 2 & informed the cashier that I'm still going to do something will come back. I'm not quite sure of the exact time I walked back in the store but what I do know is it was just before 15:00 I approached 1 of the waitresses and advised her I placed an order for sit in I am back can she assist by serving my meal she asked if I already had a table & said because it's still full she asked me to sit in the waiting area & I responded by saying, "because I'm too hungry I will sit @the tables that are by the door" she acknowledged hearing me & asked me to take a seat she will serve me. She went to the kitchen & I saw her checking on my meal thinking she will attend to us immediately patiently waited for another 2 to 3 minutes no sign I stood up again went to the counter & this time I spoke to a gentleman showed my receipt & asked if I could my meal, he then said ok it's ready so I sat down I overhead him telling 1 of his colleagues that this meal is ready can it be served the very same lady that I approached when I walked in the shop turned around to the warmer held the plates in her hand & left again and attended to a friend of her's who had walked in left my order went to kitchen prepared the ladies order within a space of 4 to 5 min's her friends order was ready & gave it her & she left, having requested for my meal 2 times I still waited then the cashier that assisted me noticed that we are back called my daughter with the receipt read the slip & said you will get it just now so as ****ed off as I was I decided to wait but after seeing that no1 was still attending to us I went to the cashier advised her I've been asking for my meal but no1 is assisting me & I was raging with anger because my daughter kept saying she cant stick the hunger anymore I've asked for my meal twice already but the lady that I spoke to has not been assisting I requested a refund after having to wait almost +- 15 min's for a meal that was long ready. Some of your staff need to be taught customer service skills and that all customers should be treated the same 😡😡
