New Delhi, Delhi, 110051

Sir/madam,
I have purchased ac on 31st march 2017, after 3 months there was problem with display, the service person came and said will take 10-15 days for change the display, mean while ac external unit was not starting,. Again we filled a complaint person came and said its pcb (Some part of internal unit) will be change and he changed it. After 10days display starts showing e6 & e5, again we lodged a complaint, person came and said its pcb is not working i was shocked because just 10days back they have changed the same part, it means either service man put that part local/earlier used part or the quality of llyod's part is not satisfactory, agin i called to customer care, they gave me the no of asm mr shashank (837693...) i talked to him and told him full story and asked him plz assure me that now when the service centre person change the pcb part they will put new part, he replied me how he (Shashank) will come to know the part is new or used, it means company gave the responsibility to that service centre which is not reliable, its realy very shocking for me, now i am feeling cheated, because now winter will start and by the next season warranty will finish and again if this pcb will start any trouble because service centre of llyod is not reliable again they will put some used part which will make trouble in future, than i have to spend money,
Sir/ madam i am using lg products and if llyod wants realy to increase the standards of service than learn from lg. I dont know this complaint will effect you or not but, this will effect me a lot.
My request you if you are changing any part you should extend the warranty of 1 year of that particular part.
My registered complaint no is hil[protected].
