RCP SERVICES GLOBAL SERVICE GROUP FRAUDULENT USE OF MY CHECKING ACCOUNT ? Nationwide

I received an overdraft alert from my bank today, and when I checked my recent transactions, saw an electronic check in the amount of $395.00 that had been charged to my account by an entity named RCP SERVICES.  No address for this firm was shown on the check, but it was endorsed by GLOBAL SERVICE GROUP to the Bank of Texas.  I have no connection with this firm, and did not authorize this transaction.  My bank, PNC, was very helpful in handling this for me, by the way.  I have noticed three other reports identical to mine on Ripoff Report in recent days -- same firm, same amount.
