Refund my money

I am extremely upset and disappointed at lyceum for adding another stress and depression into my life. I registered course and cancelled out of colling off period, the agent that called to assist with cancellation advised that I will not be refunded for my deposit, and I understood; she also said she will cancel the debit order, so it does go off my account. To my surprise they debited a full instalment that I can’t reverse with my bank, so I called and asked for refund which she said I should receive by Tuesday. Its Friday and I haven’t received my money. They have inconvenienced me, added stress to my life because now I must wonder how I’m going to through each day, I keep calling, they hang up on me, I asked to speak to manager they hang up on me. I also sent an email she keeps telling me that finance hasn’t processed the payment. What kind of a circus are you running? You’re so quick to debit people’s monies however you take forever to refund people. I cannot wait any longer I have things to do with my money, your service is perthitic!
