Unauthorised Debit

I noticed that on 25th Feb an authorised debit was taken from my account for R289 for a company called Yongimali, facilitated by Sage pay. <br> <br> I need Sage Pay to provide me with the written mandate that they received from Yongimali signed by me that gives consent to allow SagePay to debit my account. I know that legally Sage Pay can not strike a bank account without a written mandate.<br> <br> I know that Sage Pay merely facilitates the debit, but what due diligence do you have in your process to ensure that the companies you represent have authorisation to instruct you to debit customer accounts.<br> <br> I am in the process of pressing ******** charges at the police station against both Sage Pay and Yongimali - i consider this to be theft and will not take it lying down. <br> I have instructed by bank to reverse the debit, but i incur charges every time my account is debited and every time i as for a debt to be returned.
