I had cause to make a couple of minor (though not frivolous) complaints back when I was Silver. Compensation was usually 10k, and the names of the CS agents I was dealing with and the way the replies were written gave the impression it was dealt with at an overseas contact centre.
Since being Gold, I've also contacted CS twice, for slightly more serious issues. These replies I believe came from the UK, and the mileage offerings were less.
Just wondering if anyone else has had a similar experience?
