Won dla appeal how long b4 it gets sorted

Hi
I won my appeal for dla and won 2may12 but have had no paperwork other than my letter from tribunal panel on the day?? I called dla and they say they need more info?? they have sent me a letter 7 days ago apparently?? I have not recieved anything hence my call to them..During my brief conversation with them they asked for my sort code which I told them then he stopped convo and said I would have to wait for letter but he would not tell me what is in the letter and what info they still require is this normal?? they will owe me a massive back pay and im thrown back into stress mode worrying once again

As you won your appeal on 2 May 2012, the 8 working days that have elapsed since the date of the decision will not be long enough for the decision to circulate through the DLA Unit's internal mail system. Furthermore, the backlog of work may very well impact upon the DLA unit acting upon the decision, which will in all probabilities be scrutinised by a team of decision makers who will decide if there are grounds for an appeal to the Upper Tribunal on a point of law? This very rarely happens, but it is an integral part of the decision making process before payment can be released.

As to the contents of letters and the conversation you had with the DLA Unit about the progress of your claim, as B & W was not privy to the discussion, it is impossible to comment in these circumstances.
