Run debit order, never received goods

About 2 months ago I was contacted to receive an I Pad. I was at the till about to pay and asked them to call me back on Monday. Great stuff, they called back and all sounded perfect. A few weeks went by and, I forgot about everything and out of the blue on the 1st of April someone calls to ask if I am happy with the I pad I received and if all is in order ( I guess to see if they can get a debit order in...) I immediately told the call centre agent I have never heard anything since the last call and their call centre number doesn't work. She assured me that everything will be rectified and we went through the whole process again. This time round she offered services that are extra and I said she should wait with that, I don't even know about the services she is offering. She tried to explain at length but I told her to wait. A few hours later I received an sms's for the connection of the services which I immediately emailed them to stop and got no reply. I called but call centre doesn't answer/exist. I left it at that, and to my amazement I saw that the debit orders were deducted off my account. To date I have received nothing from them but R232 debit orders have been paid.
