Account Debited - Not refunded 6weeks later

PF*** & PF*** My sons cancelled their gym membership on the 28 December. A settlement amount of R 179.40 had to be paid for both of them individually for the cancellation process to come into effect.<br> Confirmation in writing that Cancellation of the Membership was done was sent on the 28 December.<br> On the 1 January my account got debited for R299 x R299 again. I called Planet Fitness advising them they could not explain why the debit went through but would request for finance to correct. I got a email on the 4 January 2016 confirming that I will be refunded in 14 working days. I called every week and was told that the payment every week will be done on Friday 6weeks later I have still not been refunded I called today and was told I will be refunded next week and that no Manager is available to speak to and that an investigation would need to be done.
