phone with repairs since August 18

I am so disgusted and frustrated about the poor services I am currently experiencing with the repairs on my handset. The handset was initially booked in on the 18th August but till today I am continously receiving useless updates that my phone is currently being assesed. The initial problem was the charging system but when I went to collect it, vodacom witbank had ******ed the whole software thus the phone was stuck on operator/save mode and nobody is managing to return it to working state. Now when I call repair call center the consultant is refusing to refer me to the complaint manager and she claims that she is the manager. I am paying for that Tablet monthly and now everything is stuck on my life because of vodacom and useless technicians. I need my phone back. As usual I am going to receive response that someone will contact me but they never does attend to our complaints. I regret ever making a deal with Vodacom. Client services is poor.
