Bad Service and system procedures

I called Planet Fitness and spoke to Casandra Mathe on the 19/12/2019 to cancel my gym membership. I was told to pay a cancellation fee in order for my membership to be cancelled immediately which I did. However I keep receiving sms's that my debit order will still go out on the 30/12/2019. I sent an email querying this and spoke to Casandra Mathe again and was told that unfortunatly the debit order will go through and I should reverse this. Why should I pay the bank fees for reversing the debit order ? Casandra Mathe advises that if i do not want to reverse the transaction I will have to wait 14 working days from the debit order date in order to receive a refund and that refunds are only done on a Friday which would make the refund date the 20/01/2020. Their system sucks !!! I paid the cancellation fees so cancel the debit order !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
