ILR set 0 to ILR long residency

[mharoon79]

Hi Every One
I applied for ILR on the basis of 5 years route on 24th June 2016. HO asked for following documents

• Wife's english certificate: 18th Dec 16.
  Questionnire Self employed : 20th April 2017
  Wife's 2nd finger prints: 24 Aug 2017

All above documents were sent within Time scale with Signed Delievery
I have not recieved any further correspondence since Aug 2017. It has been frustrated to wait such a long time for decision . All documetns were geniue including tax document with no ammendments
My 10 years completed on 6th September 2016. Should I switch my current application to Long residency 10 years route?
Please Advise.
