Unauthorized debit order deductions

I did not enter into a verbal or written agreement with this company yet the following amounts has been deducted from my bank account with the following reference:

DVotion ********** Sage 190416 deducted 17 April R105 18 February R105 15 March R105 My bank gave me the following of the debiting company: 012- ********** ********** They confirmed the Dvotion is not their client.

I must continually reverse the debit order at the bank or pay an amount to my bank to stop the debit order.

They also have an website without any contact details and a bogus face book page

Please assist Regards Leon
