Hp - HP Battery replacement

I have an open case number ********** which has been opened from **/**/**** and it's really very disappointing that my issue is still not fixed. And i have been running diagnostics for the battery and still my issue has not been resolved yet, When i ran the diagnostics i face the battery fuse issue after that i was told that i need to pay more than *K to replace the batter which is legit even having a HP care pack which is still ACTIVE and not expired yet and which clearly says i have a battery replacement free with the HP CARE PACK, I am student who is pursuing for the MBA and i hope HP should understand how much need would be there for a working personal laptop of mine which is not been purchased a long time back and i have started facing the battery issue which is totally disappoint me and will think again to buy the HP products in the future. They should Either refund the amount of my HP laptop bought from the HP world or replace the battery, This is horrible and worst customer service ever by HP,
