Failed to link my Vitality and over charged my acc

There is no customer service at Planet fitness after you signing the contract. They only care about signing new member and don't care there after. I joined under vitality package and they never linked it and over charged my account and they don't care. I came countless times to fix this but they just promise, but keep over charging. Stay away from this The Wedge Morningside branch, because they gonna over charged your account, and promise to sort it out untill the amount increases. When u ask they say call call centre number, which they also couldn't assist.
