Really Vodacom??? Again!!

It has been 3 weeks and still I haven't heard anything from the store or Vodacom Head Office. I have been told that they are still "working" on the problem, I am STILL paying the installment every single month, and I still don't have my phone back. I would really appreciate if anyone can just let me know what is happening with the phone or they must give me a new phone, I am really now tired of waiting on a response and not getting anything from them. I personally feel that it is very unprofessional and unfair. Is this the way Vodacom treats their customers? If it is, I will name and shame as far as I can and tell people not to do any business with them because they have poor services!!!!!
