Upgrade disaster

Upgrade done online 11 Jan 2018. Mistake on Vodacom’s side and processed as new contract in stead of upgrade – phone had to be returned. New phone sent the following week, but never received as courier got hijacked. Had to wait 2 weeks for new phone while investigation was done. Finally got the phone, only to discover specifications completely different as to what was advertised online. Called to mention the problem, situation was escalated to Ashley and was promised a new phone with specs as advertised within the week. Waited 2 weeks (despite numerous calls enquiring about the hold up and no clear reason being provided, apart from that the problem was with the courier) for the collection. Collection was done on 15 Feb and to date (11 days later) still no information available on when I can receive the phone I was promised. Numerous calls made to Ashley and told every time that matter is escalated and waiting for authorisation within the next 24 hours. Matter was escalated to Kelly at head office on 23 Feb, apologies made and feedback promised by today at 11AM – no call. Tried to speak to Ashley again today (as I have no way of getting in touch with Kelly directly) and told he will call me back and that he is working till 8pm. After no call back (as has happened numerous times to date) I called again after 5 only to be told he is not available and I need to call back tomorrow - ie. refusing to take my call as I know he was still on duty. All I need is some feedback. It has been over 6 weeks since upgrade started and I am still without a phone!! Beyond disappointed and frustrated.
