I am so tired of being harassed by CSS Credit Solutions!!!

3rd complaint about CSS Credit Solution. I know that I'm going to receive their default response. "We apologise, we will look at it and someone is going to contact you"

What do I have to do for this company to stop harassing me? I sent Vanessa Applegreen and Busisiwe Vuma proof that I do not owe Tyme and Tyme has confirmed that I dont have default payments and yet I'm still receiving this:

Payment Arrangement Default TYME Bank More Tyme Account, No:
