Worst service

I ordered a half mixer and a bottle of milk. Once I placed the order I was notified that the hand mixer is out of stock. I had no option to cancel the order which is disgusting because if you can't deliver everything I ordered then there is no point as I still need to go to the shop myself and I have to end up paying R35 delivery for a R17 bottle of milk. *******. I won't use your service again.
