Staff lies so get commission and and HR disappears

We were ******* into signing up for a membership at a price, have written confirmation about the price, the very first debit order was more than agreed upon, i immediately reached out and was told it was an error and they will fix it, also went into the branch and spoke to the sales manager, this was in end February, now in April still no feedback or issue resolved, the only feedback given is that the agent who signed us up got fired and the case is at HR for review regarding our membership. a mail as sent to the HR by the sales manager on the 20th of march and still no feedback. I've called head office about 20 times, left 4 messages for Ryno Strydom who does not get back to me at all, Yesterday when i phoned the office the receptionist confirmed he is at his desk and transferred my call to him and still no answer, customer support refuses to give me his direct email as they apparently share one email address with HR, Ryno and support. Ethan cant give feedback, Customer support cant give feedback, Ryna is unreachable, Eslin's extension is never available, the club cant do anything. How is it that such a big company is failing at something this simple. Its been since 26 January since i first reported this matter and up until 8 April absolutely nothing has been done. No wonder people give warnings about Planet Fitness
