Took money via debit order on cancelled contract!!

I signed up with ADT and was told that they would come and install their transmitter on my alarm system within 3 days. After 6 days I hadn't heard from them and tried to call the consultant on the number that he provided. Could not reach the consultant as he just hung up without answering.<br> I then decided that I was not going to do business with a company that offers such poor service up front and called their call centre to cancel the contract. But on 1 March they submitted a debit order and took R397.00 out of my account.<br> I have called them numerous times now to have my money refunded. I'm collecting reference numbers but I still don't have my money back. They have no right to keep this money because I informed them timeously to cancel the contract -- within 7 days -- but they continue to demonstrate their disdain for their customers.
