RCP Services Global Service Group Created an electronic check with my name as payee and removed $395.00 from my checking account. Internet

Discovered a check for $395.00 had been deducted from my checking account.  It had been electronically created using my name and stated that RCP Services was the authorized signatory for me.  Never heard of this company nor of the endorsement of Global Services Group.  It was to Bank of Texas, with the last 4 numbers of the account 2165.  Immediately contacted my bank, changed all my accounts, and it has been reported as Fraud and Theft.  Where did they get my information??  This occurred April 5, 3017.  I plan to authorize my bank not to honor any computer, electronically created checks in my name.     Nancy,  Indio, California
