Since I have subscribed to one of your magazines, there have already been 3 claims in 5 months. The copy does not arrive and to top it off when they forward it to you you have to wait another 15 days, and luckily if it gets home, why one of the times they sent it back to me after 15 days to the post office. For that one subscribes?
If they don't change and are more professional and provide better service, they will hardly get us to re-subscribe again, a shame.
