Samsung S6 Edge Repairs - No Feedback

<p>I took my S6 Edge in for repair at your repair centre in Canal Walk. I have paid for the repair. I have tried getting through to that repair centre to follow up on the repair status on 4 separate occasions - on hold for up to 15 minutes at a time. I have emailed your offices 3 times - nobody is responding. Any feedback on this issue especially considering that when you required payment I was contacted but now that I require feedback I have hit a brick wall?</p>
