very poor customer service

On the 3 june 2015 I. Approached intec college welkom branch as I want to study bookeeping with pastel. They lady working there gave me all information how to register I had gotten all the neccesary documents and had taken it to her she then told me she would call me the following day to let me know when I could go and pay my deposit into intecs bank account she never called after two weeks I called her then she said oh sorry yes you can go pay. So I went and paid my deposit . After a month they hadn't taken off a debit order yet so I called the lady again so she said she forgot to tell me that I needed to bring proof of payment to her so the following day I took it to her she then told me that the same day I would get an sms with a student number and then within 28 working days I would receive my books it has been four months now I haven't received anything yet when I call intec call centre they don't know who iam they don't know where my money is no one gets back to me when I go to the lady in welkom she just pulls up her shoulderss and tells me she doesn't know what's going on. What should I do?
