Still not resolved

Planet fitness are STILL deducting money from my account after I instructed them in writing to stop. Received an email from them saying they tried to call me without success and referred me back to the same call centre that told me to email customer services.... I have still not had a satisfactory explanation about the four fold increase in fees nor have they explained how they calculate the cancellation fee, or told me how much it is (I'm assuming it has changed since last month when they gave me just 24 hours to settle). Utterly disgusted by their contempt for their customers. WORST GYM EVER. DON'T USE THEM.
