I have recently purchased( on 17-05-07) one NOKIA N-72 from Uniflame Equipment, Guwahati. the set has developed some problem and i had requested the Uniflame Equipment, Guwahati to get it corrected through an authorized agency. They have given it to Bharali Service Center, Guwahti who has rectified the defect and charged me Rs. 390.00 (Rupees three hundred and ninety only) even the set was under warranty period. They have told that set is infected with virus and it is mandatory to pay for virus cleaning even the set was under warranty period. Uniflame requested them to waive off the charge but they did not agree and forced me to pay the amount. Is it a legal payment?
