Poor Service and Waiting for Refund

To say am angry and disgusted with Mr Price Mobile is truly an understatement, this is too much and now I need compensation for wasting my time. I bought a phone 14 February from Saltriver Cape Town, 11 March the phone stopped charging took it to one of your branches sent it for repairs, it came back collected it after 2 days it stopped charging, sent an email to Mr P Mobile support 29 March 2 people responded that they will get back to me none of them did. I had to make calls no assistance or whatsoever. I went to Mr Price Saltriver spoke to the lady and she explained that she cannot process a refund without authorization from headoffice and they haven't received any of my emails from their headoffice, fair and fine I left. I contacted Mr P mobile again all they could tell me is we will get back to you you.. On the 9th of April a manager from another branch contacted me she was helpful but I told her that unfortunately what I need is my money back and she couldn't assist further because I didn't buy it from her branch..On Friday I received an email that someone will contact me but nothing from 29 March till 13 April still waiting. All I need is my refund nothing else.
