Failure to acknowledge payment of account

I wish to warn members of Planet Fitness, especially when it comes to their method of handling payments and contracts. I use to be a member of PF but will seriously advise people to stay away. As per lockdown, they decided to freeze the account for 6 months, which did sound nice but then the surprise came. They started deducting in 2021 again, which was fine and dandy, but after February the started deducting on the wrong date and I kept on saying to them the last day of every month (which according to PF is the 28th). In June they collected on the 28th (again wrong date) for 3 months instalments, and once they collected the money handed me over for collection so that I have to pay the same 3 months a second time. And when you speak to the collection company Saya they refuse to acknowledge that payment was done and I just have to pay again. I asked for a statement and was told that one would be send the same day I found them which was the 26/07/2021, nothing happened. I phoned on the 27th and was told it is going to take another 2 days for PF to create a statement and then send it to me, there seems to be no record. How is this even legal in out day and age, ask a statement and get it within minutes, go to any bank, any business, except for PF that needs 2 days to create a statement.
