DO NOT APPLY FOR LOAN WITH THESE ****MERS

If I could, I would have given them no stars. I got a loan from them and my repayment date was the 12th of March but the started calling on the 11th. Harassing and threatening me to pay. To my surprise they even showed me my phonebook, like me phone contacts, Is that even legal? I have asked them to remove me from their data base cause they are scanners and they are not professional.
