My advice is save the appliance box until it is out of warranty. I too had to box up a vacuum to ship. It was not easy, nor would I want to do it again.
Secondly, the companies are not responsible for picking up the appliance. That service costs more. They could make an exception but what is to stop people that can get to town/Fedex from taking advantage of them. They do have to draw the line somewhere.
You may live where there is a car service avaliable for people in your circumstances. Check with the local senior citizen's center. There may also be someone who could help you box it up. You can also check your church. Many church members wouldn't mind doing something like this for you if you ask, but don't take advantage of this service. Those groups do not take kindly to people that want to basically use them for all of their housework for free. There are paid services for that and family for those needs. They can then question if you are capable of living alone and not in a care home.
