Dear Alex
Unfortunately I can not help with your questions with regards to Jet 2.
I also wanted to apologise for the response you had. Not all British people are like this and I try to treat people the way I would like to be treated. More often than not I have been working or training with different cultures and in different countries who generally have made me feel very welcome and have been very helpful.
I hope you have better experiences in future and wish you well in your job search.
P.s enjoy your wine and wx.
