Las vegas athletic club Lvac Charges fee at different times, claims there are insufficient funds, then charges more fees Las vegas Nevada

My husband and I bought two memberships for the Lvac in 2015. We signed up for automatic payments on two separate accounts.  Lvac does not charge the accounts at the same time each month, which results in the account being charged in the beginning of the month, the end, or even multiple times in the same month. If there's any issue with the payments they charge a late fee, regardless of when you pay it. A few times they claimed that there were insufficient funds and charged the account a fee for that, around $25 per account, even though there were sufficient funds. When the bank was called and asked if there was a charge applied to the account at the time of "insufficient funds" they had no record of said charges. One month they charged the account three times, including late fees. When Lvac was called about these incidents they (after much haggling and speaking to managers) were able to void 3 charges, but for all the other charges they said "there are too many voids on the account" so there was nothing they could supposedly do. There were only 2 emails in the span of a year emails saying that we were late paying, or the payment bounced back, even though they send other emails confirming our payments. The rest of the times we received no emails. Recently, on the last month of our membership we called to pay over the phone and tell them we did not want to renew our membership. Lvac said that we would be paying late fees for this month. There was no charges on either of our accounts, I checked our balances as we were on the phone with them. We told them that there were no charges on our account from them, or any messages from the bank or the Lvac saying the payment did not go through. They again said that they couldn't waive any more fees because they have waived to many already. We asked to speak to a manager, but only got number to call back later. In total we were charged over $250 in fees for Lvac's incompetent billing and dishonest practices in the span of 2 years, on top of the $1100 we were initially paying for out membership.
