Hopelessly pathetic service.

I wanted to purchase an item online from Makro. I had to first register an account with them. I tried numerous times to enter my address, but s wrong address kept popping up. I eventually just gave up, yet a Makro agent phoned me abd I told her to cancel my registration as I've ordered the item elsewhere. Now I get these stupid junk mails from Makro, Game and Cash and Carry. I've unsubscribed from them every time they sent me this junk mail, but they just keep mailing me their *******. Come on guys, please remove my details from you system as I'm not interested in dealing with a bunch of pathetic characters that can't even manage their website and mailing system properly and keep irritating me with their ******* junk mail.
