Online Orders taking over 2 weeks for delivery !!!

I am super disappointed with the service I am receiving from Makro Online shopping. I placed an online order on the 6th of April that consisted of balloons and a big load of alcoholic beverages - an order of about R1200. After about a week or so my balloons arrived. As for the alcoholic beverages - NOTHING. I am still waiting... The reason for placing this order so long beforehand is that I need it by the 26th of April for a birthday party - it cannot be later than that ! And I could never have imagined that something like this can take so long. I have phoned multiple times, agents promised to phone me back, which was just another disappointment as I am still waiting for that phone call. I only recently started doing business with Makro online, but if this is how the service is going to be, I will not return, nor recommend anyone else to do so either. VERY DISAPPOINTED
