HP India — hp is pushing to purchase their very costly ram for upgrade & applying service charge for ram upgrade

Address:

HP Care, JM Road, Pune

I recently purchased a new hp laptop from tata cliq. It was of 8 gb ram so i wanted to upgrade it to 16gb. I tried contacting hp care & they told i need to purchase it from hp stores only. I enquired about it & found that hp is charging 3-4 times higher rates as compared to the one available on other sources like amazon. So i again contacted hp care and they told that they won't install the ram which is not purchased from hp store.
After that i talked with hp care branch manager, he told he will do but around inr 500+ gst would be charged and there is no responsibility of them if anything wrong happened to the laptop post ram installation.
In such case, customer mandatorily have to buy from hp stores. This is basically to make money only.
