I receive 10+ calls a day from Kay Jewelers, is this harassment? Other Debt

Attempts to collect a valid debt generally are not considered harassment.
Perhaps you can obtain a loan to consolidate some of your debts into one easy payment?
You need to find a solution before your credit is destroyed.

 

A simple way to stop the calls, change your number and don't give the new number to anyone.
If debts are weighing you down, think about bankruptcy.

 

Return their jewelry. That will go a long way.
