Reg Gst returns after applying for cancellation

we have applied for gst cancellation nearly 6 months back...

no intimation from department... still the status is pending for approval ..and it have gone to "Central"..

I have continuously raised greviances on the portal..
the reply was to contact the jurisdiction officer ..

I have tried the same and searched for number in the contacts section available on the portal..but it's of no use..

what can be the best alternative ( apart from filling of returns till date becoz it's have been pending from department..if department had found any disparancies they could have sent the application for resubmission to rectify our mistakes..there was no call from them even...how can we bear the late fee ) ..

thanks in advance
