Month Long Wait for Charging Issue!

Beginning of 2015 I took my phone in to the George Pnp branch as it wasn't charging. 2 weeks later the phone arrived with the entire casing replaced. At home I put the phone on charge as it was not switching on.Half an hour later I tried to switch it on. I realized it was giving exactly the same issue I gave it in for (not charging). The phone was never tested for the actual issue I sent it in for. I returned it to Vodacom and it was sent away again. 2 weeks later, I called to follow up as I'd not received a job number. They told me I could pick up my phone at the Garden Route Mall branch. The next day I called their branch and asked them to confirm they had my phone. They told me it had already been sent to the PnP branch, so I went to pick it up. The staff at this branch had no knowledge of the phone being sent to them, and called the Garden Route branch again. They were told work had not even begun on the handset. I was finally given a job number (***0) and am now still waiting for the handset to be returned a month later. This is completely unacceptable as a contract customer who has now paid for a month in which I did not have a phone!
