Orbital Publishing Group, Inc. multible renewal notices, most mags. not even delivered. Internet

I am writing in regards to my 93 year old father who has sent thousands of dollars to this company. Right now I have 8 renewal orders totaling over $1000.00 for mags. he does not even get. This has been going on for years but I just became aware of how bad it is because I have had to take over his bill paying. I called some months back and was told 1-I can't cancel these orders, 2-he has some coming for the next 5-6 yrs.. He was even sent to a collection agency for one of the ones we didn't pay, even when I said we wanted to cancel. I'm at a loss what to do. My father has never not paid his bills and this whole thing is very disturbing for him, he always says to just pay them so he won't look bad.
