Waiter not giving good service

On Sunday, 12 July, we went for lunch at Cappuccino's in Clearwater Mall. I ordered the chicken schnitzel with mushroom sauce, vegetables and cream spinach. I only had one schnitzel, half of my vegetables and half of the cream spinach. I asked the waiter to pack the rest in a take away. On Sunday night when I wanted to have the rest of my lunch I was VERY surprised and disappointed that only the schnitzel (dry) and cream spinach was packed!! NO mushroom sauce or vegetebles??? VERY bad service as I paid for this food and honestly only got half my money worth!!!
