Pathetic Service

I had subscribed for a 6 month subscription with Cosmopolitan, it was pert of a package that was offered for an even that they hosted. I only received one magazine from them. When i queried this i was told that my subscription ends in September and unfortunately they do not have copies of the May; June and July issues that was supposed to be delivered to me. I find this extremely disappointing and unacceptable as i paid for a 6 month subscription and only one magazine was delivered to me.
