Castle Pay Day Loan

am in a lot of debt and i am using a Debt Relief company to ease the stress of my debt. An online pay day loan company started contacting my family who i never listen as references when i took the loan, stating that my family should give me an 800 number. They also gave my family members a TN Court claim number. When i called them, they were very rude and tried to harass me for payments and threatened to serve me papers and take me to court because i have not been making payments, although i had made payments for 6 months. They also stated that they wont work with my debt relief company. My question is, can they really take me to court? I also attempted to settle with them telling them how much, i could pay, but they laughed at the amount and told me that they would see me in court. Please advise.
