Sabc tv licence

Good evening! I have a problem with sabc tv licence I paid settlement amount in march with sabc yet they still call me telling me I'm owing them R1000 -i asked them why I'm still getting messages on my phone to pay the amount that is in arrears.when I tell them I paid in March already they keep telling it's not yet updated on their system and I asked them who's fault is it because I'm tired of your phone calls telling me I'm owing.ive realized that the more you pay it's the more they keep nagging -Please Peter help me with this sabc tv licence department.
