ESA to UC transitional -

I was told by the help line to send of the UC application on 13th May, as it was due in by 15th March. There is a bit says ..up till 19th March somewhere in the letter? I did it on the 13th, for whatever reason it kept telling me the on line verification was in correct , so I had to click on call back for verification. They said they would ring in the next few days in the Journal. Then I got a message that they would ring Monday the 19th. My worry is, will this affect the transitional payment , as it's still highlighted I have yet to agree it all? I had to have an advocate help with it all, it's far too complex for my issues, the whole system of it. regards

Oh sorry, tired old me,

I meant due in 15th May. not March?

Today I received a letter , deadline extended to June. I have no verification call till the 19th. What chaos might this cause to the transition please?

regards

Okay,
thanks David,

I see so many people on forums that are subject to DWP errors with it, just worry I do.
