Horrible Customer service by Flight attendants

On 22 Aug the Morning Flight of 7.20 Flight FA750 from Or Ar Tambo to Harare , We had the most horrible experience with the 3 Flight attendants , their customer was so bad and very rude , Only one lady who mentioned she was new was at least pleasant , It was the first time for a lady i was sitting with and she said is this what it is to be in plane , ordering food was like we are being a nuisance to them . On departing i asked the names and there was Martina and Parusha and the one said she didn't have a name - like really i took her frown face a foto ,,we felt very much as though it was an attack of all the Zimbabweans on that plane as we all agreed that it was the bad customer care when we left the plane , I am sure you teach them customer service regardless of which customers they are serving . You can contact the other passengers . I am sorry for coming late i just remembered this horrible experience because I am trying to book another flight .Thank you
