Sir, I bought a Maruti WagonR Lxi on 07 June, 2011 from D D Motors, 81-A Rajpur Road Dehradun Chassis no 265716 and Engine no 7040632. On the same day (07.06.2011) I got installed a maruti security alarm NCS-1209 by Mr.Sanjay Sardul (technician), DD Motors. On 19th July, 2011 the horn of security system opened automatically came on the belt of the engine in side the car bonnet and damaged .this i came to know when i got the car checked by Mr Indrajeet at maruti true value DD motors but he also could not tell where it was fit what happened.I think this was not properly tightened by the installer (Photographs of damaged horn attached) and shows his carelessness. This instance brings down the quality, satisfaction, reputation of company and belief of customers. Please go through the matter and get my accessory replaced or what else may be done. waiting your quick and positive response. thanks and regards.
