Terrible customer service

I wish there was a rating below the current one star. I am awaiting a delivery of a parcel. The delivery was arranged last week already and confirmed. I needed to do something else which i moved due to the delivery. My appointment which was emailed and communicated is to be between 10 am and 12pm. Its currently 13:48 and i have been calling since 12:05 following up on my delivery. i have made 4-5 phone calls and no one can give me a concrete answer and the only update they give you is the driver has not updated as yet. I got really annoyed and requested to speak to a manager and i was transferred twice and disconnected. The only customer care consultant that had the courtesy to give me a call back after she said she would follow up was Oratile (THANK YOU SO MUCH) for actually considering a customer. After my last attempt to speak to a manager i finally got a call back from Head Office and was advised that the driver is somewhere stuck and will be here after 2. i find this extremely annoying as i was not going to be this annoyed had someone called me prior and advised the driver might run late. But it took 4-5 calls to follow up to only get a response that made sense. I FIND THIS ANNOYING, that an appointment was made and there was no courtesy taken to advise that there is a issue
