I have a personal account on Sony website where I register all stuff I buy from Sony, last august while browsing I had a pop up asking to reply to a (long) survey, when I finished it I had a message with a coupon code to use for my next buy to get 20% off. The code is supposed to last 6 month but everytime I try to use it it says "not possible" to use, blah, blah... It is only for accessories according to the website that day. I asked for help on french twiter but they don't give a, they asked me for the email from sony but I got no email, the coupon was just displayed on the website page and that's it. What can I do to be able to use this 20% off ? french support is inexistent, only automated reply by email...
