Debit order issues and a wrong Monthly subscription of R199 with a penalty fee of R20 every month

I am disappointed and outraged with Planet Fitness Valleyview krugersdorp, I was called by Head Office in October 2023 due to unpaid payments, I run a small business, sometimes my suppliers pay month end. I then requested to change my debit order for R199 from the 25th which belongs to my 15-year-old Son to month end of each month. The agent assured me that he had done so on the system and made a a mistake of not asking for a reference number.but surely cause the calls are recorded they able to pull the call,I then made a payment of R438 due to my arrears. To my surprise on November, I received a debit order on the 25th, even though I was assured that my debit order was going to be on month end of each month. So I ended up paying R220 Via EFT as the extra R20 is a penalty fee. December the same problem occurred and I called Head Office on the 4th of January to escalate the matter and the agent assured me again that they would fix this problem but said they couldn't do anything about the debit order of December and I was told to pay the fees I owed which were R220 again, and the reference number for my call is PQF/68528 Arthur Lukele, I clearly stated to the agent that I will escalate the matter to Hello Peter if the matter is not resolved and he clearly stated that I am more than welcome to do so. When my son went to the gym yesterday(26 January 2024)he was told that his tag was blocked due to R198 owed and advised that he should come with his parents, I did so today(27 January)when I dropped off my other son at the gym(who hasn't been having the same problems with his account)as I went to complain about the matter, I was advised that I must pay R198 today and pay again on the 1st of February which I find ridiculous becausei am not in arrears,they also advised that rather i must call head office again and i then I told them I am going to write a review to Hello Peter and I was told once more that I am more than welcome to complain if I am not satisfied, so cleary this matter isn't going to be resolved anytime soon . It so humiliating for my son, his tag is always blocked and he is always paying R20 extra every month from his lunch money.I was sold a lie as my monthly subscription is no longer R199 it is R220

I would please like Hello Peter to assist me to get this matter resolved
