I gave a camera for repair at this authorized centre. the camera was taking blank pictures.
They told me i would have to replace something for Rs2500 (camera cost was about 6000).. i told them to go ahead... they repaired and i noticed a drop in picture quality. to make it worse, the same problem reoccured after a few months of repair.
They are there just to sell parts and do not have any idea of the problem or skilled labour.
