Lack of service delivery and communication!

My cellphone contract was due for an upgrade, I dealt with online consultant Celeste who processed my upgrade. When it came to the delivery address, she was unable to populate the address on the system, I mentioned a landmark thinking that a note would be made. I was told that the phone would be delivered the next day as Vodacom has a 1 day delivery policy. I never received my phone the next day and I had to contact them to find out that my order has been placed on backorder as the phone wasn't in stock, 5mins later, the phone was in stock but no nano SIM, I asked that the phone be released without the SIM, again delivery will take place the next day. Later that night I received a back order SMS, contacted Vodacom to find out that releasing the phone with out the SIM is a problem and that the order will need to be cancelled and reprocessed, few mins later i was told that the phone will be released with or without the SIM, again delivery will take place the next day. Well, with the delivery address incorrectly captured the delivery vehicle now can only deliver the phone tomorrow, 24 July 2015!!!! I have never in my life battled so much to do an upgrade like this! TERRIBLE SERVICE!!!
