Harassment

I'm sick and tired of the Foschini Group from Cape Town harassing me. They call me 20-22 times a day, whether is morning or evening. They've got no respect for my time calling me at night or very early in the morning. I keep saying NO for whatever they are selling but it seems as if they are not bothered with me not wanting to subscribe to a magazine. Many times they just call, when i answer the phone, they just drop the call or keep quiet. I've had it, I'd rather close the account I have with them than me having to go thru all this.
