India Post — delay in pli surrender wb-264883-b

I had submitted a surrender request at park street hpo on 7 june 2017. But even after complaining many times, i have not got my money. Then finally i submitted a complaint at post office website complaining about the delay and they closed the complaint the following day asking me to wait further. I have already waited for 2 long months. For how many more months do i need to wait to get my money. Complaint registration no was [protected].
