Made f&f of £10000 now ivs company say 6 months to issue cc and I presume pay creditors a share should ivs company be paying intrest on this large amount of money they are holding for months as it must tun int0 many many thousands they are holding onto if not seems very wrong to me .
Complain as such a delay should have been declared as a material fact and would have been a consideration for any offer that you made.
IVA started March 2011, Completed March 2016 and certificate issued 11 days after final payment. It was not always easy but then some of the best decisions aren't.
Interest is nominal - I suspect hardly anything is being received in interest however you might find its in a non interest bearing account in any event.
6 months is a little long however for closure so keep the pressure on them to handle things quickly.
