Professional Couriers - Package Not Delivered

I'm Pavan, I have sent my CCTV Hikvision DVR Box through Professional courier tracking number WGL****** on **-AUG-****
from
Warangal Telangana
to
Sirsa Haryana.

When I called to sirsa branch his number *********** he said delivered on **-AUG-****. I called to my destination address he said not received your package then again I called to sirsa branch asked what is the proof he said DRS sheet missing. Up to ** days I called daily one reason telling till now he not provided any proof of package. He blocked my number.I got so much irritate with their service. I dropped email to professional courier and complaint also registered but no response from them so many days past. I called to mumbai corporate office to professional courier no response.

I gave complaint Professional courier in warangal Telangana
on **-SEP-****. They enquired to sirsa branch but he said DRS sheet missing. In warangal branch they said we kept complaint to New Delhi and will call to Hyderabad further they said here.
