Spice Jet Airlines — poor handling baggage lead to broken bag and missing power bank!!!

I am writing this with a heavy heart as i am a frequent traveler from spice jet.
I took a flight from surat to bagdogra on 14th oct 2018 (Pnr: y3fs9b) which was a connecting flight. From surat to delhi it was a pleasant flight as usual my baggage was in intact condition. After that i took a connecting flight from new delhi to bagdogra as soon as the flight landed at bagdogra i got my bag which was completely destroyed by your luggage staff (Pictures attached), which is simply unacceptable because earlier neither the bag was in poor condition now it was old. That was a brand new bag and your staff completely tore it. The horror doesn't end here my power bank was also missing from the luggage which was also a brand new one.
What is this spice jet, can you please tell me is this the way to treat your loyal customer.
