TERRIBLE AFTER SALES SERVICE

I received an sms that FNB was trying to contact me to finalize my GOLD FUSION account. i received this card in April and have had no issues thus far. i called the number ********** 880 and no one seems to know who i should speak with neither were they of much help. i received an email as well and responded and im still waiting for a response. I DO NOT APPRECIATE BEING THREATEN THAT MY ACCOUNT AND CREDIT WILL BE REVOKED! someone needs to call me urgently and resolve this. FNB!! WHAT IS WRONG WITH YOUR SERVICE THIS YEAR???
