Rude call center agent.

I placed an order online with Makro big mistake . The first time I called the call center to track my order I was promised delivery on the 21st. Then there was no delivery I called again and I was promised delivery on the 24th. The 24th has passed and still no delivery. Today I called the call centre spoke to a very rude consultant who just wont let me speak I ended up cutting the call as its was just plain useless for me to bother explaning.I would really like to know when am I getting my order.
