I bought a heat pump a year ago and i've been having problems ever since. my latest problem is that the pump is making a loud noise that my neighbors are compiling, I have been trying to get someone to fix it since December but they keep dragging it. I have a case manger who contacts me every other day but she is helpless and just wastes my time. today she called i couldn't pick up (had lecture) so she left me a voice mail saying that she closed the case because i didn't answer the phone!!!!!!!!! how rude. i really dont know what to do, i have warnety. do I have legal right? the pump costed us so much money
