Unauthorized debit order

11-12-2017 I received an SMS which was informing me that Usizo 247 debit of R115 sold by KEYDIRECT will go through and I was surprised as I had never had any contact with the above company,indeed the debit went through on 22-12-2017 but I have since reversed it and blocked them but I find such act ******** as I had never had any agreement with the above company
