No response from WeFix

I wish I could someone to answer a phone at any of the branches I have called (namely Canal Walk, V&A or Gardens). Seriously urgently need to get my phone fixed and the response is seriously lacking. My back camera glass has shattered and now the camera is not functioning. I went to WeFix Canal Walk (at their request) to have the phone checked. I was told by one of the staff that the technician was going to source the required part and that I would be contacted. To date no call and I have been trying to call this branch and others and absolutely no response. My insurance works with this supplier and hence my hands are tied. I have also posted to the WeFix Facebook page and still nothing. A response of any kind would be appreciated.
