Online shopping nightmare

I decided to make use of Makro's online shopping site. There was no problem selecting what I wanted but the problem began with the checkout process. When I got to the delivery address section I was told to enter my suburb (postal code) from the drop down suburb menu. The only problem was that my suburb was listed as being in Gauteng when it's actually in the Free State. The postal code was also completely incorrect. I therefore had no confidence that my order would be delivered to me. There was no option to enter the correct details so I phoned the customer care line. The operator there was unable to help me and quite frankly did not seem to understand what I was talking about. I gave up in frustration and had to then select the option to go into the Makro Vaal to go and collect my order. This is extremely inconvenient as it is a -+ 35km round trip and the stores are very busy at this time of the year which is exactly what I wanted to avoid. Come on Makro - make your online shopping experience more user friendly!
