Unhappy with this company

This company must stop harassing me, they are calling me telling me that they want to help me to reduce interest on my debts, and they send an SMS saying i gave them a go ahead to run a credit check for me that I did do. This company must delete my details, I am not interested to their service **** they then decided to drop the phone because I was telling me them I am not interested and I am fine with what I am paying.
