Confused about ESA result/or not ?

Hi , Im wondering if anyone could shed some light ? With the help of this good website , I filled in my ESA50 form which had to be sent in by 19th May , 2016. From then on, Ive heard nothing , until this morning ! This morning (19th January 2017 , 8 months later) , I have received a letter from the DWP which is headed ...YOUR CLAIM FOR EMPLOYMENT AND SUPPORT ALLOWANCE....CHANGES IN SOCIAL SECURITY BENEFITS. It states that from 10th April 2017 , the rates of some social security benefits may change. On the back page (page 3) it works out how much money Im entitled to being in the WRAG group , and it will apply from 11th April 2017. So , my question is , is this the DWPs way of saying that I have been awarded ESA in the WRAG without having to go through the misery of a medical ? This has never happened before as Ive always had to attend their medicals. If it is the case that I do not have to attend a medical , they havent sent me anything to say how many points I scored , or where/how I scored them. What should I do next ? Anything or nothing ? If I have been awarded ESA WRAG , I dont even know how long it is awarded for ? My last award was for 2 years but I did have to appeal to get it back in October 2013. Any advice would be appreciated, many thanks. Kind regards , Wendy.

Hi Gordon , thank you for informing me that my name was showing , and that I have now corrected it. I hate having to contact the DWP , its like disturbing a hornets nest ! I will give them a ring and I will let you know the outcome , and for the benefit of anyone else who maybe in the same predicament. Thank you for replying to my query. Kind regards , Wendy.
