Device not received

I took up a contract with Vodacom November last year. I app**** for the contract online however I never received the device and when I queried, I was told by the courier company that the device was lost. I contacted Vodacom as they continued to bill me for a contract for a device I did not receive. I have literally been pushed from pillar to post. My profile is now in Collections. I advised Vodacom of the events, and everything has been acknowledged and is on their system records. I have escalated this matter; team leaders and managers were suppose to get back to me and resolve the issue. I have till now not receive any feedback from anyone. When I phone in to follow up no one knows what is happening, yet your system records are updated!!! This issue has been going on for over a year. Your service is beyond pathetic. My credit profile has now been impacted because of Vodacom 's poor service delivery. Again, last week I received notification that my account is in arrears for a device I never received and a SIM I never activated because I didn't receive anything. I called Collections, they said I must speak to Cancellations, the cancellation department tells me they can't help me I must speak to collections as they are not able to assist me, but you know very well how to send me notifications that my account is in arrears for a device that I never received. Can this issue be resolved or put me through to someone who can resolve this matter.
