Dont get what you pay for!!! No response!

I have purchased a camera from ebucks - I was looking for a package that would provide me with the best value. ebucks had one package -with an additional camera course and a bag that did not have the camera make name on the outside of the bag......the package was roughly R1100 more than the offer on takealot (who by the way - also deliver within 24 hours), but for the aforementioned reasons (course and bag), I made the purchase from ebucks. The purchase was delivered 10 days after the order, and upon delivery, I realised that the bag which was delivered as part of the package was in fact not the one advertised on the ebucks shop. I have called to make the complaint and was informed that someone would call me back to determine the best way forward...still nothing!!! the question being raised here is - why should we try to support on line shopping - when you dont get what you pay for and, when you complain...nothing is done to rectify the situation!!!!!
