Bad service I received from the call centre

I've been calling since Monday to find out where's my order till today no one has answers since everyone is saying something different. I spoke to Muzi, Tumi, Lebo, Thando, dudu and all of them did not say the same thing I'm now fighting with my clients cause they waiting for their orders and it's not the first time my order is delayed. I fail to understand how is it possible all 5of them are not saying the same thing I spent the whole day one the phone and I was told there's nothing they can do told Me drivers can't deliver in my area they been hijacked so I a asked if I did not call it means no one was going to inform me I'm so furious cause clearly they don't communicate with their raps..
