Thousand Trails review: Cancelling my auto-renewal membership

I am currently 45 minutes on hold for customer service to answer my 5th call to them regarding an unwarranted balance on my Thousand Trails account. After being a satisfied member for about a year, I called TT in early March 2020 to let them know that I would not be renewing my membership (April 1, 2020 renewal) due to the current Corona crisis. This was before I discovered buried in the 20 page membership agreement that they have an auto-renewal clause that I was Completely Unaware of.
I am Permanently Disabled and on a low fixed income and have to make every dollar stretch. I was assured the balance would be taken care of. After several weeks, and still seeing a balance of over $1, 100, far more than my initial annual membership fee, I contacted them again. Again, I was assured this balance would be taken care of and that things were taking longer due to the crisis. Again, after several more weeks and no removal of my account balance, I called again and was told to "ignore" the balance that showed on my account.
(NOW it is July) I just spoke to another customer service agent and was AGAIN told this would be taken care of and that there were thousands of cancellation requests and very few employees that were working on them. I voiced my complete disbelief and unhappiness about this taking way too long, but was assured it would be, and I would receive a letter in the mail stating it had... Still, Totally Unacceptable!
I'm posting this complaint to warn anyone who is considering joining Thousand Trails. This delay is very unprofessional and it really seems like I'm being jerked around.
Happier Trails Everyone
