Consumer Redressal

Hi, I had purchased Sony Bravia TV-Model Name-KLV-32R402A in March '14 which got dead on 1st Dec '14. The complaint was lodged and engineer visited on 2nd Decc'14 and told that a part will be replaced. Later on after having word with Sony customer care I was told that have been receiving complaints on particular model and that a new set will be provided. The engineer left without providing JOB sheet number. I had to call customer care for getting same (J43042166) and shocked to know that only part will be replaced and not set. I made plenty of calls only to get one response "it would take some time" and told to remind them of issue. Repeated emails to customer care yielded no response. On 15th, I received email from Uttam that case has been transferred to Mr Kuldeep Singh, Service-In-Charge and got call from Mr Kuldeep that new I will get new set by 19th Dec '14. Its 19th Dec, and no success. No update from anybody. Sony representatives are inefficient and lack information
