Please stop phoning and disturbing me

Can you please stop phoning me about promotions and stuff? If I need something from you I will go onto your website and order something. Stop harassing me every second day. I regret buying from you, because it seems I only made trouble for myself. You just don't want to leave me alone. Please remove me from your database for contacting with regards to promotions and opening an account. Please please please. I am begging you.
