Phone in for repairs over a month now

Brought in my Hisense (HS-U961) for repairs on 30/10/2015 and yet to get it back. When i went to Edgars yesterday(26/11/2015) to check where my phone is they tell me they only sent it to 3G mobile for repairs this week, it was sitting in the store all this time. Worse of all they can't locate my phone because \someone"did not file my BOOK IN FORM...so now there's no copy in store which means that they cannot track using my IMEI where exactly is my phone. I am so furious such an inconvenience! Now im left without a phone due to peoples incompetence."""
