Diabolical Service

I took my phone in (28 June 2015) for inspection at Cell C Westgate Mall after my LG G3 suddenly stopped making or receiving calls / sending or receiving messages. I was then advised by the Consultant at the store that I should check my phone for repairs (Job No.: PRE638788), she added that I will receive my phone within 21 working days. Seven weeks passed without receiving my phone back before I went to the store to enquire. I was then told that my phone has been blacklisted and thus would not be return to me. Even after I informed them that the phone in question was a replacement I got from Cell C insurers after the first was water damaged beyond repair. I have had no written reason why my phone cannot be fixed or replaced, or why my has been withheld from<br> <br> Since mid-August I have been referred to the Csurance and in turn Csurance has referred me back to Cell C in my attempt to retrieve the phone. All while I'm still paying my full subscription to both Cell C and Csurance.<br> <br> Attempts to retrieve the phone from Cell C store at Westgate Mall have provided frustratingly futile.<br> <br> What recourse do I have to deal with this diabolical mistreatment?<br> <br> Disgusted Customer
