HP India — Very horrible experience with HP support team

The HP will give many festival offers like extended warranty with total coverage etc. I paid for 1+3 years extended warranty but HP people dosen't care about it they are keep giving many excuses like battery is not covered under the warranty and when I contact the HP support team they said your laptop battery is in warranty and our technical member will visit onsite and replace the battery after that they keep wasting time and not responding through mail or call.
Never think that company like HP will do such type of cheating with customer.
if you can not provide the product which comes under warranty than don't cheat to customer.
Very bad experience.
