My back-and-forth with support wasn't as funny as these, but I had the same thing happen with a subscription to the print edition of Computer Music Magazine in 2019/2020.
It took them over 4 months to ship my first issue. With magazines you usually get the issue for the month after you subscribe, so I waited 6 weeks before emailing support. They told me it should have been sent, they would send a replacement. Repeat this every month-ish and after the 3rd try I gave up.
About a month after my last contact I got 4 copies of the April issue. A month later I got 4 copies of the May issue. And so on for the next year. Rather than ship me a new December (or whenever it started) issue, they just kept giving my account a new subscription and calling it a day.
