Bank Statements not acceptable as FICA proof of residence

Not accepting bank statements proof of residency as per FICA rules. Transfering money thru ShopRite Money market is like impossible, proof of residency has to be only Municipality letter head which can be forged by Nigerian ****mers as some municipality use hand written papers.. worse you pay for money transfer service & bank statement are much secure than municipality proof of residence. Why would shoprite not accept bank statements or bank related documents on money transfers ?
