Debit order date change

I sent an email to Planet Fitness just before we were able to return post lockdown to ask what is the procedure of returning to the gym and to change my debit order date to the 27th of every month and received no feedback or response from them and this was in August and I understand that at the time people were working remotely but surely someone should have come back to me by now it is November. I called the call center and they advised my debit order date will only be amended in December....this is the worst service I have ever received from a fitness institute.
