third follow-up, query still no feedback from supp

had a gym contract with Planet fitness which expired on the 10 October 2014. On the 05th September I submitted a letter notifying MY intentions not to renew the contract, however at the end of October they deducted gym subscription fee on my account and when i went to inquire, firstly I was informed that the cancellation was not loaded on their system (Which was an error from their side), I was given a reference number for that logged incidence ( ref: ***) and promised that the money will be reversed into my account however that never happened. I then followed up at their offices in Arcadia and I was assisted by Pontso who then confirmed that the contract was cancelled and that the refund would be paid into my account in the next three weeks, to date there has been no refund. i've been sending emails to their inquiry line ( [Email Removed] I am not getting any response.<br> they need to refund R165 which was erroneously billed for the month after the contract had expired. The query is being logged for the second time, after being promised by the supplier that their agent will call and to date i have not received any feedback from the supplier.
