Threat of court summons at place of business or home

Just received a voice message threatening me with a court summons if I do not contact them. His name was John Evans. He said the company is willing to work something out if I contact them. I have defaulted on several payday loans but have contacted them to see what arrangements can be worked out. Some refuse to work out an arrangement that is reasonable. I don't know which company is filing the complaint, nor did he leave the company he was calling. I've had it with these payday loans, and don't know what to do. I live in Pennsylvania.

Any advice would be greatly appreciated.
