I regret joining this gym it's the worst

The bad service i received from the gym is definitely what i didn't expect at all. I signed up with the gym on the 30th of June and then on the 7th of July i went to the gym to cancel my membership, whereas i never received any customer service from the sales person (FITMORE) who didn't brief me about the cancellation process of the contract but luckily i came on the 5th day to cancel my membership but Fitmore refused to cancel my membership saying that im late and I'll have to pay the cancellation amount. I refused to do so, then went to speak to the manager who said there's nothing he can do but he has to consult with the higher authorities and will call me on the 10th of July ever since from that I've been waiting on that call and nothing from them and then i went back to find out whats happening and they totally had forgotten about me and the manager told me that he'll have a word with Fitmore that anyone who signs up must just take over my account and ive been trying to get hold of the manager and he is always not available. I regret joining this gym.
