Rude Call cerntre Agent

I would like to someone to take this up further, I received a marketing call this morning from the following number *** the lady I spoke to was very friendly but I told her I wasn't interested. After that they didn't stop harassing me with phone calls in the past three hours. I answered to very rude call centre agent named John I told him I wasn't interested and his bluntly says why, I told him his being rude and told him I want to speak to his supervisor he said :No\\ I said you are being rude I want to speak to his manager and I want his surname
