hi folks

can i call on some help please i had a medical at atos last week for esa contribution based and i was due a payment this week on weds which didnt appear so i contacted esa today to find out why and was told id failed my medical no information as to why so i said i would like to appeal and was told i would receive an appeal pack.really worried about finances all day today (which wasnt helping at all) i rang back to see where i went from here a very nice lady on the phone from esa pointed me in the right direction and told me to write my appeal letter as she had booked me an appointment with my local job centre tomorrow to take it in and have it emailed to speed up the proccess.she also assured me that i would still be paid while the appeal goes through so this was a weight off my mind.could someone help me with some ideas on what to write as i have never done this before and dont want to screw it up

thankyou
