Did upgrade 01/08/2017 and still do not have my cellphone in my hands. No customer service from them, no following up with clients and no delivery.

I did an upgrade on my cellphone contract on the 1st of August 2017 and i was told 3-5 working days for delivery by Nombuso a agent. After 5working days and no delivery, i called to hear what was going on and when i will receive my phone, i was told that they have changed courier services and that there is a bit of a delay with my delivery bt someone will call me back. Another week passed and i was getting upset so i called again. Spoke to nombuso who then let me speak to kim her manager as i said i want to file a complaint, she said my ordernis being escalated and that someone will call me for delivery. I gave them another 7-9days and nothing. Then the morning i wanted to call a delivery guy frm dsw called me and said they will deliver the next day and the driver will vall to set a time. The next morning at 10 o'clock i phoned dsw and asked them are they still going to deliver and they confirmed that my name is on the list. After waiting and nothing hapening the next day the 23rd of august i phoned dsw and asked hem what is hapening, they explained that my ordernis there but mrn has to release it for delivery. I phoned mtn upgrade department again and they said no my package is at the couriers and they will phone me for delivery. I was livid and did not want to continue upsetting myself further so i left it. On the 4th of september i phoned again and spoke to joshua as i was at a diffirent branch. While on the phone with him, he phoned dsw himself after i explained my story and he confirmed that they have my package and that they will phone me soon to arrange delivery. I phoned dsw after talking to him and they said they have no package for me with them and the one that they had with my id number on but wrong name they sent back to mtn for repackaging on hursday the 31st of august. I phoned mtn back and they still said that i must wait and let them phone me for delivery. So now i phone again to hear whats going on and everytime an agent picks up i ask for joshua or nombuso or kim they say oh there is one let me put you through, when someone answers its a total different department and they of no one with these names. I have been with mtn for 9 years and never had any problems at all with them, i always faught if someone had something bad to say about mtn and their service as i had never experienced it myself. Today i am considering to get info to go to another service provider or to hear what anybody else suggests about the situation. This is my first time on hellopeter.com and i realy hope i can get some help and advice on what to do. I am realy livid beond angry....for he whole month i kept my cool and tried to stay calm and i am a very inpatient person and i do not have patients....but when do you draw the line with this type of bad service from somone you have never experienced bad services from. Please help me to get this to where it must be and also help me if possible with any kind of advice. Anyone is more than welcome to contact me and help me resolve this as i have never delt with a situation like his in my life.
