Delhivery — Parcel missing and no support

I have booked a pickup parcel from Gwalior to satna by delhivery and after some days when i got msg that today parcel will be delivered but no parcel came then i went to delhivery wear house and found that my parcel was not present there and they assure me to give them 2 days for issue resolving next day i got msg of parcel delivered.
I went a lot of times to delhivery wear house but still they are unable to track my parcel and i issued complaint as well on delhivery website but now no complaint showing.
No support by delhivery no contact no given no reply by their executives.
