Very Disappointing service

I have experienced such poor Customer service at Courier Guy! Once again one of my parcels has gone missing. When I contacted the Depot this morning I was assisted and they sent a Courier Guy to meet me at the locker to see if the parcel was still in the locker. It wasn't. I was told I would be contacted after 2pm today after they had tried to locate the parcel at the depot. I did not get a phone call. When I tried to call them I spent over 21 minutes holding on and was cut off twice! I have now had to, at MY expense, create a new order, pack new product and use more petrol just so that I can get the order to my customer who is waiting for it. I had R100 airtime on my phone this morning and now have only R16. When you phone The Courier Guy you spend more time listening to a voice recording and never seem to get through to anyone, when you do you get cut off! As from previous experience I doubt I will hear from the Courier Guy about my lost parcels. Just like in the past I was guaranteed I would hear from the Courier Guy about my misplaced parcels, months ago. I'm still waiting. I am a regular customer and have sent close to 13 000 parcels in 2 years so we spend a lot of money with you for this ******* service when I need good service the most! Now my customer won't get her parcel timeously and I look bad.
