Extremely frustrated

I joined planet fitness platinum in January 2017. I had no problem with my membership until inquiring about cancelling my membership. I requested via email to cancel my contract once it expires so that I am not charged thereafter. I received no response to my email and so I called the call centre. I was told that my contract only expires at the end of January 2018 and cannot request to cancel it until then. I thereafter received a reply to the email I had sent stating that I may cancel my membership immediately but would be required to pay a cancellation fee. The amount was stated in the email and bank details provided. The email had requested that I do the payment within 24 hours or it would no longer be applicable. I did the payment immediately and sent the proof of payment to the email address stated in the email. After a week I had still not received a response and called the call centre again to inquire. I was told that they had not received my proof of payment and asked me to send it to another email address which I did and received no response once again. I then called again after a couples of days to see if it was received and was told that it had been received and that the cancellation was processed and I would no longer be charged a monthly membership fee. This whole process was a great inconvenience to me but I thought that it was finally sorted out. This morning (29 November) I received an SMS for a debit order deducting my gym membership fee from my account. I am extremely frustrated and disappointed and I will never recommend planet fitness to anybody again due to the very bad service and inconvenience which I had to deal with.
