Frustration-verification status

i sent for d verification for roll no 106071.. They send me back a letter for verification of roll no 106070.. They have posted with a note on top of d original address of roll no 106070 which has my address.. Name is of 106070, address is mine.. Which has been stuck on d org address of 106070.. I have sent a letter back statin d same.. Frustrating.. I dint expect my result to change, but i did expect d verification to b carried out..
