Hi,
this is standard practice, it is normally identified as a "60 or 90 day request" before they start the final processing.
Our consultant gave us PDF's with current data, all that we did was update any changes and then return them to the
consultant.
My advise, get them done ASAP, we messed about and lost time compared to others. The quicker you get them in the faster the medical request will happen, if your application is successful.
I would not cancel authorisation at this point, in any case you have most likely paid them most of the money, right?
Cheers
Bob
