Planet Fitness nightmare- Administration of changing bank accounts- incompetence

OK. We closed our bank account from where Planet Fitness received a payment every month for two memberships. On 10 JULY--note- 10 JULY 2023 .....we immediately sent them notification of this change- PF*** - and again 14 July -PF*** and then......All necessary signed documents to change bank accounts were completed and sent, 2 August- debited from wrong account again and we informed PF of this again! on 2 Sept-PF*** we inquired again because no action was taken, and then again it was followed up- 10 Sept after no correspondence, my husband instructed PF to remove the debit order from the CLOSED account, no response again and again deducted from the OLD/CLOSED account end of Sept and obviously no payment went through, now we are in OCTOBER- then I went to Waterkloof Ridge and filled in the change of banking details AGAIN AT THE GYM (note -it was sent in JULY via email already) and on 6 October (low and behold) we received a phone call- at last- then I made a payment on 7 Oct 2023 (07;00) at OLYMPUS branch as requested for OCT because PF did not change the account. I paid for two memberships and was told they could not provide me with a receipt- the system had issues and today is 12 Oct- still no receipt) Then I wanted to train at Waterkloof Ridge branch- we are on a national membership-- MY WORD!------ I was blocked from access to the gym. Payment went off our account on 10 OCT and we have communicated now every day - I must now proof that we paid(Olympus could not provide a receipt) it went off our bank account- I have sent the payment proof and the last 4 digits now to BOTH branches. Good heavens-- This has caused us as members SO much inconvenience now and we are made out as trying to not pay, where PF has received payments from us every month and for 6 months I could not train because of a severe ankle break- so you received quite a good amount, and so far PF received their payments religiously every month. Why is this so difficult-- Oh yes- please do go and listen to the telephonic recordings as well where we tried to resolve this matter now over 4 months now.PF- get this right now, please!
