FAILURE TO ACKNOWLEDGE CANCELLATION

i took up membership with Planet Fitness on the 29th of January and thereafter was not convinced that the gym will satisfy my fitness requirements and as a result i attempted to cancel the membership well within the 5 day cooling off period stipulated in the contract. I then drafted a letter stating the reasons for my cancellation and then handed it over to the Parklands branch as per the contracts requirements. i was then informed by one of the reception ladies and subsequently the branch manager that customer services will contact me regarding my cancellation. it has been exactly 2weeks since I sent through my cancellation and have not been contacted by a single person from customer services. After numerous times following up with the branch regarding the cancellation i still have no answers, I need to know whether my cancellation is being processed. And need to remind Planet fitness that the cooling off period clause states that all monies paid need to be refunded WITHIN 15 working days after the cancellation has been submitted to the gym. Please ensure that this takes place as per the contract!!!
