Slater treat their customers like *********

I have a contract for me and my kids. My daughter and I don't gym because some of the staff treated us poorly. But that's not the issue now. My son usually gym at SW5. He lost his card a few weeks back and made a new one. Today he wanted to gym at Rocky Slater in town. They treated him like a ********. They said the card is not on his name, he stole someone's card. So the staff at SW5 made a mistake and put the new card in my name, instead of my sons name. And they said our membership was in arrears . Which was funny because I have a debit order. They said it wasn't paid in September. Now you see the problem is if I had known there was a payment missed I would've paid it. But no one ever told me this. So for the past 8 months no one could of just said to my son at gym there's a problem? Even when my son made his new card they didn't say anything about this. So now my son got treated like a ******** for something that was not his fault. Now he has to pay again for a new card because the staff gave him the wrong card to begin with. And this is not the first time we got treated poorly at Rocky Slater. Just when I took out the contract and went there the first time not to gym but just check everything out, we were told we cant go in because we dont have towels. I wasn't there to gym, just to see how the gym looks and how everything work. The lady embarrassed us, that's why I don't gym. I'm only paying the membership for my son to gym. But after today I'm seriously reconsidering my contract with you guys. I'm so disappointed
