Never had to ask for my money back from a gym. But what do you do when there's no lockers available and it closes in 30 mins? As in anywhere. Asked staff twice for help and got none. Went to the front desk and was told it was my fault. She almost wouldn't give me my money back, but she could see I was ready to cause a scene so she gave it to me... Worst gym ever.
