The worst service ever

I placed an order on the 28th November 2017 with the promise that I will get delivery within 7 days. I do not get any response from the store even after I called the store the whole day either leaving a message for the people in charge being promised they will call me or not getting through because the phone rings and nobody picks up or it rings and gets cut off. In the meantime my airtime gets depleted and they don't care. I was also told some customers were in the store fighting with the people in charge. Not my problem, I need my staff for this Saturday. I thought buying online will be convenient, I do not recommend buying from Makro Online, worst service ever!
