WRONG QTY, BAD SERVICE AND COMMUNICATION,

This was my first order online with Makro and will be the last. I ordered two items and was very disappointed when Makro advised me that they will be delivered separately!!! But I did get them in one delivery. Then one expensive item was the wrong quantity half a litre instead of ONE litre (which cost over R100). I tried to log online a return but it is not working. I phone them and log a return. I have a reference but no confirmation whatsoever. I phoned them again but they told me that I must wait at least 24 hours for the confirmation of my return. It is just very bad customer service and communication.
