Bad Service from Fnb ***** department. my account is blocked because the call centre agent advised that they suspected ***** on it. she gave me the e-mail address of the person ( Aphiwe) that i must email the information to so that they can unblock it which is not involved in *****. this was on the 29th Dec 2020 and up until today i got no response from Aphiwe. on the 5th i called the call centre again to do a follow up, the agent tried to call the investigator department and there was no response , she then sent an an e-mail to Aphiwe and his/her manager to follow up and request that they call me back, and up until today i am getting no response. my account is blocked, i am not able to use the funds that i have saved to use during this difficult month, no one is responding to me or giving me feedback. please assist me
