Refund not paid

Varsity studios has not processed my deposit refund till date. I app**** for my refund on the 3rd of December and the contract I signed states that it will get processed after 21 days and it has been 5months .I have checked with them for more than 4 times excluding the unanswered emails and calls. I’m told that the manager has not started working on refunds . The contract has been breached on their end and the irony is ,they literally lock you out of the building if you have missed a payment by a day because of the ‘signed contract’.
