I got a "free trial membership" to Yahoo Greetings (which is actually American Greetings) 2 years ago and I've been trying to cancel it ever since. Membership is renewed automatically, so I've been between $13.99 and $15.99 per year since registering. During this time, I think I've sent exactly one card.
The free trial membership says that you won't be billed if you cancel before your 30 days are up you will not be billed. There is nothing on the site's home page that tells you how to cancel a membership.
When you click the help button, and go to "All about my paid membership," there's a link that says "Can I cancel my subscription" you get a phone number to call. I have repeatedly called the phone number. It is an automated system, and the 4th or 5th choice instructs the caller to say "cancel my membership" if the caller wishes to cancel. I said the words "cancel my membership" but it didn't recognize my words. So I tried again. Same result. Then it said that since the voice wasn't being recognized, it will change to a push button system. I waited for the "cancel my subscription" option to come up, but it never did! The only way to cancel is if the computer recognizes your voice, but it never recognizes your voice! That astounded me.
Then it kicked me off the system. I called back. I got the same result all over again. Finally, I decided to test the system by trying out the voice recognition system with another feature, so when the option to say "technical assistance" came up, I spoke "technical assistance" into the receiver, and unbelievably, it recognized my voice! My voice hadn't changed in the few minutes between calls, but the computer apparently can recognize people who want technical assistance but not people who want to cancel their membership. I've never seen anything quite like it.
Finally, I was in the technical assistance menu, but I had to scroll through many choices before I got to the "wait for an operator" option. It consistently recognized my voice throughout those menu choices. When I did get to the "waiting for the operator" part, the wait took about 15 minutes, there was no music to let me know I was still connected, so I often thought the line had gone dead. After the 15 minute wait I finally did get an actual person who canceled my account and credited me with $13.99.
This was the third or fourth time I tried this but was the only time I was successful.
I looked online and discovered that many, many people have had the same problem. I hope something is done about this.
