ABSA HR IS DE*****ING ME SENDING IRP5 TO SARS. I DON'T WORK FOR ABSA

Absa have submitted IRP5 to SARS and am no longer working for them, SARS has been sending me correspondence that I owe them R6000 when I investigated the reason it was said that absa has sent them this IRP5 and I DO NOT WORK FOR ABSA. I have sent numerous emails to ***ca but no one responded and when I follow up there's nothing it's been weeks and weeks and SARS want their money by the 20th. Where am I suppose to get that amount honestly?? Times are hard and absa I just making it worse I AM VERY FRUSTRATED ..ABSA HR IS *****ING ME.
