Feedback, Response, Non Delivery

After my first complaint on Hello Peter two weeks ago (three weeks after handing it in for repairs for the 2nd time within a month) it took less than 24 hours to get some progress on my issue, however, I was not happy that Vodacom wanted to replace my faulty phone with a second hand refurbished phone after I spent R7000 cash for a NEW phone that I only had in my possession for 4 out of over 12 weeks as its been in repairs twice so I insisted I receive a new unit. I was then told on the 10th of July that I would be receiving a brand new unit - I hope that is what I get - but now my problem is this, another 10 days have passed & still no phone. I again had to follow up myself on the 17th of July just to be told once again that they are waiting for the manager & supervisor at escalations to advise. ANOTHER 3 days gone & again still no update, I just keep being told they waiting, waiting, waiting. Waiting for what? Waiting for who? And why is everyone just waiting instead of doing something about it? I was told by the shop that sold me the phone that it would take 7/8 days, Vodacom told me it would take 2 weeks max, but I am now heading into the SIXTH WEEK since handing the phone in!!
