I’ve been using their Top-up service for a little while now and it’s never failed. However, I purchased an iTunes gift card from them and got the code via email. When I went to redeem the code, I was prompted that the code has already been redeemed. I contacted ding someone called Martin responded asking me to contact iTunes when ding was the one that sold me an invalid code. Please avoid them at all cost. They’re a scam and lying scam bags.
