SBM Motors — Jupiter gave for service not giving back

I gave my Jupiter service on friday, 4 days over still they are not giving back and not doing service also and not giving proper response also.
Daily they are saying tomo..I doubt some suspicious thing happened to my scooter.whether they are changing all original parts . I doubt whether to repair one scooter they need 5 days.

I dono what to do. Pls take some necessary against delear so that other customer will not face this again.

Thanks,
Sujay
