National Home Gardening Club Discontinued my magazine subscription, which was supposed to be a lifetime subscription. Minnetonka Minnesoto

I was told when I became a "life member", that I Would be able to test products.  I did one or two product tests and gave an un-favorable grade to the product.  They did not send me any more products to test. 

I have tried to contact them, with questions about different garden problems, and have never reeived an answer or even an acknowledgement that my question was received.  I paid for my life membership in full, which was supposed to include a lifetime subscription to the magazine "Gardening How-To".  I received the magazine until about this last Spring, then it stopped.  Haven't received it since about April.
