no sense of work ethics and customer Service

I recently purchased a mobile handset on 01:10:2015 from edgars within 4 days I noticed the device being faulty and still within the out of box failure when I took the device back to the store a consultant that has no clue as what she has to do .and after showing her the faulty I was rudely told there's nothing wrong and they have to send the device away till this day 10:11:2015 I haven't received my device which I payed cash for. After contacting the store <br> More then 87 times of which I only got hold of someone 9 times. I feel that Edgars doesn't want to take responsibility as I had to buy another phone because I use the device for and received warnings from my work in this regard and all im being told is they sorry and they will get back me it's more then a month and still no response.... because they feel its ok and appropriate to treat customers this way .....im seriously disgusted in Edgars and how im being treated... running Around begging them for feedback and response.
