NON EXISTING CUSTOMER SERVICE

I have been struggling with Planet Fitness since last year. First, I had trouble in cancelling my black tag with them. Then, after months of struggling, they finally cancelled it. Then, out of the blue, they started charging me for a black tag again this year. Plus, they overcharge me, saying that I do not attend enough gym sessions. The manager at the branch itself checked my statistics and indicated that I have more than ample training sessions against my name! I have been reporting this problem for the past eight months, yet no one is doing anything! Customer Services would send me an email, stating that they have spoken with me and that the problem has been resolved, without even really speaking to me! Then, after phoning them AGAIN and holding the line for more than 30 minutes, they said that I will be credited for the additional money which was taken from my account. Three months down the line, I am still paying double and sometimes even triple the amount I am supposed to pay! No one listens and they do not care!!!
