Harassment

I keep getting phone calls from two numbers that I believe belong to the Foschini group. The numbers is *** and ***. They always start their conversation with 'because you have been such a loyal customer...' now i have been patient and calm the first 2 times... Telling them I'm really not interested in their insurance or life policy ****!!! I asked them nicely to remove my number from their phone lists... Now I'm getting rude because how many times do you need to tell this people I AM NOT INTERESTED... They even phone at 21.00 at NIGHT!!! Sundays, Saturdays, public holiday. I'm working full day and i am really busy at work. Personal phone calls is kept for emergencies only... Please this need to stop! I will never buy a policy from a clothing company!
