I WANT MY PHONE

Long story short: 3 August i took my Samsung Note Edge in because i had no connection. After numerous days... or rather about 2 months, Vodacom said they had blacklisted my handset(s). After telling me i owe them R20 000, after I've paid vodacom their false accounts per month of over R20 000 since Jan 2015. I had someone investigate who came back and said R2700 then I have paid my 3 contracts in full. Hence the handsets are mine! After paying the R2700 I got told my phones will work within 5 working days.... guess what!? 2 months later and it is still not working!!! So now apparently coz I am \in arrears"with vodacom"
