H.P.
I was able, years ago, to get a gym membership reimbursed, a few years' worth of monthly payments. I had joined with a friend some years before. There was the free period and then that automatic paid membership following the free period. Then, the gym ownership changed, and that changed the price. My friend and I fell out.... It was a mess. I even had a hard time just cancelling it! I was young and needed some money, and I was grieving a string of family tragedies, so I used all of that to plead my case. They sent me up the chain, and I was consistent and kept up with each call and was in tears or on the verge each time. They finally sent me a check. I wrote a big thank-you note to the last woman I talked to.
