Debit order issues

I was stopped at tag-in 3 times after starting to gym at planet fitness, for my banking that had an issue on the system. I made sure the banking details are correct and uploaded on the system.<br> <br> I was contacted in February(two months into my contract) and informed that my account was overdue. I then inquired why this happened as I signed a debit order and there is no reason for the debit order to have failed, and received no answer.<br> <br> Then payed the outstanding amount the same day and was charges a service fee for the debit order not going through. There is no reason from my(the client) side as to why the debit order did not go through therefor i refused to pay the service fee. The assistant in the gym responded to my dissatisfaction with; she can not help me and I need to take it up with customer service. I then sent an inquiry to there customer service and have still not received a response.<br> <br> I see that there are many issues with there finance department(complaints on hello peter). This is unacceptable and I would like to be responded to when I have a query as that is what customer service is and considering that this is an issue on the companies side.
