PANDORA - Wrong item delivered and radio silence for three weeks and counting

I ordered online, but got delivered the wrong item. I sent an email timeously advising them with photos. I did get an email that there is high traffic/busy period and bear with them for a reply. However two weeks later still no answer, resend email - same responses. I then visited a store and was kindly after verification put in contact with the regional manager (not online) who has also struggled to this date to get a response from their online business. It is now three weeks and counting and have not heard from Pandora, and now I am too late to give the correct gift timeously. (will be a belated gift if Pandora ever responds!). I am highly disappointed as am an avid supporter of their jewelry. Hope this reaches them and creates a response and action.
