Very bad service

I upgraded my contract with MTN Direct on the 2nd of November and they confirmed that there is stock available for my order and that the phone (Huawei P8) will be sent to me, I will receive it by the latest 4th of November. I called them on the 4th late afternoon and they said the phone is on its way. On the 6th I called again and a women very rudely interuptet me while I was busy talking and told me I will receive the phone either the same day or on Saturday 7 Nov 2015. Today 9 Nov 2015 I called again and the operator said that his supervisor will call me shortly after I attempted to cancel the upgrade as I am willing to go over to another service provider. This is the 3rd consecutive upgrade where I had nothing but bad service, previously also used the service of Hello [URL Removed] . I have been with MTN since my first contract when MTN started in SA but if this is the way service is going I wound rather walk over to the competator for a contract. I even wanted to take out an additional contract that we don't even need in order to get my wife a new phone but I guess that went down the drain aswell.
