Honda 2 Wheelers India — Honda sp 125 warranty problem

Dear sir,
I purchased honda sp-125 on date 11/06/2021 from sharda honda showroom Raigarh Chhattisgarh .When engine malfunction light showing on in my honda sp-125 bike, i went sharda honda where i purchased my bike, technician checked and found that electrical cable found cut beneath the petrol tank, they give approxmate cost of 3300 for replacing whole electeical cable of bike and when i asked for warranty of that parts then they told that, cable was cut by mouse and warranty is not applicable in this case, how can service center fool to customer by just replacing all the electrical cable of bike for just 1 minor cut of cable just beneath the petrol tank.
