HP India — wrong motherboard installed

Address:

Ghaziabad, Uttar Pradesh

i brought a laptop 2 years ago from HP certified showroom under the warranty of 1 year. --- Webcam in my laptop stopped & i complained, it was replaced within a week but wrong hardware was installed (my laptop is of 40, 000 but the hardware installed was the one which comes with 20, 000 rupees laptop) then i called again with issue & right hardware was installed next time... ---few months later my wifi & bluetooth started to create problem & i called HP again then they said the whole motherboard will be replaced since this problem is deep, i said okay do it & make my laptop work again...they changed the motherboard & laptop started working fine ---i have 1 year onsite warranty which means that the motherboard & webcam hardware was changed at my home in front of me... now the problem is that my graphics card was of 2GB ATI RADEON HD7670M initially i didn't checked but later i got to know that the new hardware is 1GB, half of my original one & my CPU used to provide performance at 6.9 but after changing it provides 6.1 which is a great fall in performance & GPU is half of original... all i want is right motherboard installed again so that i can get the value for money... ---motherboard was changed 1 year before & then warranty ended...i stopped playing games then & didn't noticed it but from last 2 or 3 months i have started playing games & doing heavy stuff and my laptop is not providing performance i was promised... ---please resolve this issue as soon as possible & i have receipt of wrong webcam installed and then right webcam installed & then motherboard installed...i can provide all 3 receipts to you as a proof...!!!
