Please Assist I need my money back.

I app**** for a cellphone contract on th 1st of September, I spoke to a consultant who read the terms and conditions in the T&C it stated that there is a once off fee of R150 that will be deducted in your account only when you receive the cellphone which will be after 7days but I first need to send the 3month bank statement. I sent the 3month bank statement on the 3rd of September however later i received a text stating my application was declined. On the 30th September Intelicell debited the R150 once off fee in my account. I would like to findout why? they can go back to there recordings and listen to what there consultant said to me. I do not have a contract with them i need my money please. The worst part they have a blockage in the account so I can`t stop, dispute or reverse the debit order which means they debit every month.
