hp support warrantees no good laveregne Tennessee

My computer was giving troubles so I contacted hp support. They said computer was under warrenty so They sent box so I sent computer to them. A couple of days later they call to tell me my computer not under warrenty due to water damage. That computer has been in my bedroom because I'm handicap and I guarantee it has been no water around it. I feel like they are a rip off just trying to get money which I refused to pay. I will never buy another hp computer. Every time I called support had to talk to somebody from India. There support really sucks...
