I bought a Karbonn K25 mobile from Twins Mobile Shop,Trivandrum.One month after found a line on the display after two weeks that increased to three lines.I approch the that shop.they said not doing service here and want to bring the mobile at "Minnus Mobile" also known as "Karbonn Care" ,Mass Tower,Attakulangara,Trivandrum.I bring my mobile to that shop,on 09 June 2011 ,they received and gave a receipt and request one week for the service.Till this date they didnt gave back.When To day also I called to Minnus Mobile on the number 0471 3243726, one lady pick the phone ,she said need more time and said contact to office with number 0471 3224242.I called that number but they did not gave any satisfactory reply.
