Shapiro Shaik Defries & Associates

I was contacted by Shapiro Shaik Defries & Associates yesterday regarding my exact account that was in arrears i asked for a amount to settle the account and thet said that i have to pay 5700 but later the afternoon just to confirm they gave me a different amount of 6138, i paid it this morning and hope to receive a paid up letter im afraid of struggling 2 years like other people that i read about they harass you for payment but cant get back to you on questions you asked
