Order not being delivered

I was supposed to get my parcel last week Saturday delivery guy called me and tuned didn’t come to my address and he said I was unavailable…..today I called the office there are saying my order is out for delivery but I have received any SMS and no one called me when I asked the office lady why I haven’t an sms if the order is really on it way she just said she have no idea,what a bad service I’m angry I wonder why Telkom is still using this courier it service
