Spice Jet Airlines — boarding pass issuance staff misbehaving

There is 9kg hand bagage, but they pushed hard to place the laptop on luggage but i denied. The spice jet staff made 3 attempts to irritate and finally i given my cover to indigo passenger while boarding my flight. This is reddiculous and you can check cctv on 13th from 8:15- 9:45pm. I don't want to travel with spicejet in future and will inform my corporate offices to don't blacklist spicejet.
I want to know some action plan from you on those 3 staff
