Primefin stock market company IRRITATION

This is one of the most irritating companies on the entire planet. I visited their website once and had to fill in contact details on the website in order to proceed . A consultant from Primefin then called me and I politely stated that I am not interested and was only browsing. Eversince I have been getting numerous phone calls from Primefin every day and after repeatedly saying that I am not interested and that they should not call me again , they still keep calling. Some of the consultants are rude and verbally aggressive over the phone as soon as I say that I am not interested - “BUT YOU PUT IN YOUR CONTACT DETAILS ON THE WEBSITE , WHY THEN DID YOU PUT YOUR CONTACT DETAILS ON THE WEBSITE” in broken english and with a foreign accent . They still keep calling , and I don’t know how to make it stop. Advice to you - AVOID THE PRIMEFIN COMPANY BY ALL MEANS!!
