Massage Envy

I moved 18 months ago just before the Covid lockdowns. After Massage Envy started re-opening I had a very difficult time booking and to make it worse, the closest ME to me is 25 miles. I now have 13 sessions and have been trying to book new ones at any of 5 ME that go from 25 to 55 miles from me. The freeze form they want me to sign takes away my right to sue so I won't sign it and they now have my account frozen so I can't even try to book a session. Now I find out that when I signed up and my monthly contract called for $39.00 a month, I should have been grandfathered at the level permanently. Are they any class action lawyers that are currently taking Massage Envy complaints? If it's true about the grandfather clause, I could be owed thousands since I became a member in 2010.
