TVS Motor Company — TVS motor company

I purchased in the year 2012 . Recently 5/5/16 done service at authorised shop. after service given lot of trouble, which are clutch plate and gears spoiled.Again vehicle took into service shop same informed to works manger. he told me that clutch plate and gears to be changed. Done the same.
my vehicle no AP 10 BD 1353 travelled km is 8000 above till date . I just want to know that for such less KM's is it necessary to change the clutch plates and gears. So I am raising a compliant against this TVS SERVICE.
