$wwks later my phonbe still not repaired

On the 11th of Nov 2015 I bough a phone ZTE at Edgars Gateway and within 3 weeks the phone gave me problems and would not sense my thumb.. I sent it back on the 11th of Dec 2015 since it was still under warranty, My phone is still not back so I made a follow up with Telkom 3G Mobile and was told that they only received my phone a month (8 Jan 2016) after I sent it to Edgars for repairs.. Now my frustration is every time I went there to check on my phone they told me the delay was with the Telkom 3G it is not back which was a lie because it was not even sent through to them to begin with.. This is the 5th week without a phone and the repair company says it might take 21days for them to repair and meanwhile I don't have a phone and Edgars does not even give you a 2nd hand in the meanwhile..<br> I want to know what to do regarding this matter and I have proof of emails communication between Edgars and Telkom 3G Mobile..<br> Im an angry customer who needs a way forward on the mistake that Edgars did
