False advertising and poor service

Yesterday I shopped on the site in the bargain box (I am sitting with a R1000 in my basket that I was going to purchase) at the time, the Bargain Box music was showing 3 for 2, initially I took 4 CD's and then whittled it down to 3. I contacted the call centre and spoke to an operator - the CD's were not discounting correctly. After she indicated that she would contact me by the end of the day - she did not. When I phoned this morning and spoke to someone else, there was no resolution yet - needless to say, at this point I am already annoyed because of service. I was then contacted to tell me that the 3 for 2 was a mistake on the Bargain box page and the CD's are NOT 3 for 2. I am very sorry but their mistake should NOT my problem and this is now a case for false advertising. When I went back to check now and the Bargain Box page has now been changed to reflect \Up to 60% Off"even though some of the cd's are not discounted at all (I smell a rat!). """
