False Advertising at its best!

Today I wasted hours of my life that I will never get back. GoDaddy.com placed an adverti*****t which I took screenshots of that offered clients domain registration at R10 per domain. I saw this a great saving and signed up two domains only to find out that they were not R10 per domain as advertised on their website but now in the checkout are R69 per domain. I saw this as a systems glitch and tried contacting the helpdesk. Long story short and several hours later the support desk told me the offer was only for new clients not existing clients and they could not change my account to reflect the discount advertised. I went back to the site and its displayed as 1 per client (took more screenshots). Nowhere is it stated on the site for new clients only. This to me is very misleading and false adverting. Be aware as i only picked this up after payment was check out.
