take it back to whoever fitted it you did go to a reputable place didn't you ? it should come with some sort of guarantee, i hope explain your concern to the person who done the work
I had a clutch changed they changed the clutch plate, the pressure plate and thrush bearing the work was then guaranteed for 2 years peace of mind ,subject to the car being inspected at specific mileages after the clutch was fitted 500.1500 3000,6000,12000 miles
