Planet Fitness even more

We have requested Planet Fitness in writing in March 2018 to cancel my wife's contract on grounds of medical reasons and we have also attached to this mail our GP's medical certficate. Although I have contacted Planet Fitness several times via emails thereafter to get response or confirmation from them that the contract has been cancelled, they bluntly ignored each and every email. After my third mail requesting confirmation from them, I've send them a further email informing them that I am now going to cancel the debit order with my bank. I cancelled the debit order and after about three months they start submitting debit orders again by simply changing the debit order detail. Thereafter we have spent many hours on the phone and by visiting their KRUGERSDORP branch. Finally their callcenter in admitted telephonically to the Krugersdorp branch manager that it was their fault as, apart from many other pathetic excuses, they have apparently send their response to our contract cancellation request to another unknown email address. I have requested them to forward that mail to the email addressed we have used all the time but needless to say that after a further year Planet Fitness still has not yet forwarded that mail to me! Now we all know, to forward a email shouldn't take you more than 10 seconds! And that is with a tea break as well!!! I am not going to waste any further time to give you all the detail of how we are still struggeling with PF to get the money refunded that they taken from us by submitting debitorders with **** references. All I wish to do is to tell ANY PERSON out there who is even thinking of joining PLANET FITNESS - THINK AGAIN!!!!!! (And AGAIN.......!!!!!!!!!!!!)
