HP India — overheating

Dear hp,
I want to complaint about service centre of hp. My case no is [protected]. I had an over heating issue in my laptop and i was complaint about this before few days about ending of my laptop's warrenty. So the service engineer came much more days to take report about my laptop for faulting to taking right report.. And so that reason my case date is extended bt my laptop issue is not solved.. Than.. As like after few weeks from service centre call me to again they send service engineer to take report about over heating. Bt some of my office issue i was out of town.. So that m not able to co operate.. Bt from hpservice centre presserised me and threntend me.. If i m not help to take them report.. They can close my case.. Bt i m not able to help so they close my case and talking with me as badly... I m very dissapointed about hp.. Plz hlp me
