Poor service and harrasment from Vericred on behalf of RCS

I have a vey bad and frustrating service with RCS with my account number ***, as far as i know my account was handed to Norton Lambrianos Attorneys and i have been paying through them since June however i am recieving harrasment calls and emails from Vericred who claim they also sent by RCS Loan, today i got an email with an attachment letter from Vericred that says they are sent by RCS and i forwarded to recoveries on RCS which still doent help as they sent me a different letter that looks **** from RCS, I need clarity on what is going on and who is suppose to deal with me as this is very childish and confusing

Both letters claim that are signed by Errol from RCS but the other looks **** the signature and the logo of RCS

i need urgent clarity and confirmation on who i am dealing with going forward and why the other company is harrasing me.
