Planet Fitness is a joke

As per my contract that expired on 25 Sep 2018 i gave 30days notice and was sent confirmation that the last debit order will go off on 1 Sep 2018. On 29 Sep however a further R290 was deducted and on 1 Oct another R320. I tried calling the call centre with no luck. I drove through to their head office only to be told the customer service manager wont see me face to face. The staff there had no idea what is going on as the system showed my acc was cancelled in Aug so now they just throw their hands in the air and i am R610 poorer for no fault of my own and Planet Fitness seems to not be bothered by it. Why should the public tolerate customer service like this?
