Med 3 and was told by DWP no time limit on appeals

Hi
Firstly: Would you know how ATOS would have got hold of a (MED 3)would they have asked my GP to send one? the last MED I sent to the DWP was a MED4 2005 which they asked me to get from my GP and to send it to them!! and can I ask the DWP for a copy of this MED3? I am in the process of appealing against the decision of putting me in the WRAG rather than the support group. and requested a statment of reasons how they had come to that decision, I also asked for the medical Report which stated the MED 3 and my ESA50 had been used in evidence in this case no mention of all the Medical Reports I sent in as evidence???

Secondly: On Friday 13th June 2012 I phoned the DWP up to ask if they would extend my 4 weeks appeal time which ends on the 20th June 2012, I asked them this because I wanted to seek legal advise and representation at appeal, the person took details and said someone would phone you on Monday 16th June between 9am-11am no one was avaiable at present, sure enough i got a phone call at 8.30 am I asked her if this was possible for extension and she said and I quote that there was (NO TIME LIMIT TO GET YOUR APPEALS in ANY MORE)??? I did Tape all this conversation and got her name I also asked for a letter of confirmation to be sent but she said there was no need that is the new rule??? luckly I have got representation, filled form in this morning and sent it Recorded delivery 1st Class (dont trust that one)???

1) I cannot work out how ATOS could have got hold of a Med3 ('fitnote') unless you sent one in. I wonder if this refers to a different piece of DWP paperwork that happens to have the same number?

2) This is the first I have heard about unlimited time to appeal. Well done for getting evidence of the conversation!

Thanks for reply Mrs Hurryback
I am still confused about the Med3 that Atos say on there Medical report that they had took into consideration in my case along with the esa50, like i mentioned the last Med i sent in was 2005 a (med4)which a made a copy of, so where did they get a med 3 from since i last sent a med in my conditions have got worse! do you think if i phone up they will send me a copy of this med3 i just dont trust any one connected to the DWP,
