WEEKLY THREATENING SMS TEXTS WITH NO DETAILS

FNB sent me threatening sms texts with NO DETAIL with just a number to call for awveral montha now. I sent a query days ago, days later I was asked for my ID but there was a ref on the email subject line and ever since that, it's been dead still. TODAY, I RECEIVED ANOTHER BUT THE SAME THREATENING SMS, NO DETAILS AGAIN! WHAT'S THE POINT OF SENDING ANOTHER QUERY WHEN THE FIRST ONE IS STILL NOT RESOLVED! STOP SENDING ME THESE NONSENSE THREATENING WITH ZERO DETAIL OF WHAT ITA ABOUT SMS TEXTS!!!!!!!!!
