A threatening call so early in the morning

I got a call from some rather hush lady 01.08.2019 around 8am. This lady was rude n harsh demanding 1500 or whatever she was saying as if it was 1million. Her tone her rudeness n the way she was soo pushy demanding it on some are u making payment today or tommorow. Like wat the hell i already pay extra 200 to cover that yet u call me like i am ignoring this. She has no manners n no business etiquette. She must go back to training. Oh i like the part where she said she will send people to come to me to make me sign an agreement letter which agreement i wonder n where she is sending them i wonder more. Basically the call was a threat on some pay now or else! I didn't know that absa has ****s working for them.
