I purchased new bike ktm duke 125 during january 2019, today i given bike to ktm service goregaon west, mumbai for first free service, so i told them add handle baar and cover during billing they should charge only for accessories not for fitting charge, they charged me 260 inr.
For this 260 rs they make separate job card and they given separate bill & mentioned any part replacement becuase in their system their is no charge for filling but they cheated me.. And behavior was rude, they don't have any explanation for this, pathetic service. Attached is all receipts for your reference
