Bad attitude

I have been receiving calls from RCS since this morning, I told the first consultant that I am not interested with the product that they want to offer me, she understood and cut the line, now am receiving call from the consultant who is very rude and disrespectful. I am busy telling her that am not interested with the product , she is keeping on pushing me and in a rude way as if am owing them. Am asking her are you forcing me to take product that I don’t want.
