This has happened now for the past 3 months and the reference number is difference each month. Since i have no recollection of signing for any new policies, i googled the company but nothing comes up. I am really concernced as to how is it that this potentially fictious company managed to access my bank account and deduct R100.00. Seemingly my money is not safe at Nedbank . </span><br style="color: #9b9b9d; font-family: 'Source Sans Pro', Verdana, Geneva, sans-serif; font-size: 14.4px; line-height: 20.5714px; text-align: justify; background-color: #ffffff;" /><br style="color: #9b9b9d; font-family: 'Source Sans Pro', Verdana, Geneva, sans-serif; font-size: 14.4px; line-height: 20.5714px; text-align: justify; background-color: #ffffff;" />I would appreciate someone looking into the matter ASAP as i did not authorise any debit orders and i regards this as a ********** matter.</p> <p> </p>
