Disgusted at my experience

I am disgusted at the two flights iv taken with mango Thursday that passed and yesterday. I had to make someone pay with it with their credit card and paid them back. But was it worth it?? No! Going to Cape town on Thursday morning with Mango was absolutely disgusting. The service was pethetic as if we are doing mango a favour. There was arrogant staff that didn't assist me with water, I was ill and needed water. The lady without a name badge made me wait until she made money selling chips and coffee to other passengers. She kept on saying the water is very warm and I should wait. Coming back to Durban yesterday was even worst! I informed Bianca one of the cabin crew members that there is ****roaches below my seat. The disgusting part is that I came home with 2 ****roaches. How is this acceptable???? I do not take Mango flights I was introduced by it by someone. And this is what I got. Leave alone how my bag zip was broken when I collected my bags. I went to the customer service desk at king shaka airport to complain. They told me sorry " it happens" what happens? Messed up service or for uncomfortable treatment. I am going to take steps further. I may not be a frequent flyer with mango but I'm sure to get respect and get treated like a frequent mango flyer. Now I ended up paying the guy who bought my flights for me thru his credit card. All for nothing!!!!!!! Money doesn't grow on trees. And coming from a hospitality background. Yourl need training on customer service??????
