Appliance Matters

I got my dryer broken and I got their guy to fix it, he told me there is a part that need to be replaced but he doesn't have it and he can fix the existing one for now and if it didn't work I can call them. It got broken after four months and they refused to carry responsibility because it is out of warranty and I paid another 300$.
Three months later it got broken again and they refused to carry responsibility because it was three months and two days and their warranty is just three months.
