Unauthorized Debit order or by Direct Comm :-(

I got an SMS on the 29-01-2019 confirming that i will be debited R129.00 on the 31-01-2019 By Direct Comm for my Viva Lifestyle that was apparently sold to me Ref nr BD ********** 190131 . Their contact number is ***. I was given an option to reply with CANCEL to stop which i did same time

No one called me and sold me any product or service , that R129.00 was debited on my FNB account today 31-01-2019.

I feel so cheated, unprotected, angry and worried about my credit profile that will be affected when i reverse that debit order.
