Unfairly being black listed by planet fitness

I would give planet fitness a 0, but it doesn't go that low, although their service does .our granddaughter lives with us, she has no work so doesn't earn a wage or salary.we decided to pay for her to join the gym at lifestyle centre parklands Capetown the sales person did not explain the contract in full, gave her a buddy tag, which put the gym fee up to over R600. I spoke to the manager, David, in January, he promised to have the buddy tag removed ..it never happened .since February I have contacted David's manager, no less than 40 times to get this issue resolved ..this manager promised the buddy tag was removed and she gave our granddaughter another 2 months free But, February and march they still tried to take over R600 from the account..The contract was cancelled as they had gone against the contract and all the promises were.not kept, costing more calls from us, e mails, and bank charges for stop orders ...Now we have been told that the contract has been cancelled but we owe R1800 for early cancellation. If this is not paid they will black list out grand daughter...she has no job, we are pensioners, how can they charge R1800 when their job was to just remove the buddy tag and get the debit order down to the amount as agreed by Marissa and David .I know I am old, but, I'm far from stupid and I know for a fact this gym was visited less than 10 times in over 3 months. I don't think the managers and head office accounts have correct communications otherwise this would have been resolved the beginning of February and our grand daughter would still be going to gym there I have e mailed head office, I have asked several times for the regional managers number, andre meyer, but have been refused access to speak to him...I want to know why? Is he untouchable? All this drama because a manager couldn't get accounts to remove a buddy tag and keep the gym fee at the original amount agreed on..R499. I would appreciate any feedback from someone at planet fitness that has authority to resolve this 3 month issue . Obviously their sales personnel at the gym just want sales without checking if the client has work or can afford it .. this is so wrong in everyway..and when a person is let down so badly they get black listed?? Planet fitness needs to retrain their staff from the top down to the bottom...the manager at this particular branch has told me today she can nothing about the cancellation fee, obviously not as she couldn't even get a buddy tag taken off...my husband and I are disgusted at the treatment and disinterest shown to us regarding this issue ..they just don't care, they take the money then lose interest. Where must we as pensioners find R1800 when the branch at parklands caused all this drama, and why the threat of black listing a young woman who has no job? Bullying or harassment just because they can't read e mails, or communicate properly ...when they do respond they are automatically on the defensive. Please planet fitness get your act together and do the right thing by your club members ....
