Thuli is disgusting, unprofessional and rude

Fin well this is seriously frustrating I can't be getting calls from you guys everyday. Thuli from your company spoke to me as if she is speaking to her child and I was never rude I only asked her to remove my number from your system because I work in a call centre and I can't keep getting calls coz I can't be on the phone. If this is how you guys speak to clients and there is seriously something wrong with your company.
