Isabella Garcia had been debiting my account, but I have not received any products from them

Isabella Garcia had been debiting my account, but I have not received any products from them. I cancelled the debit order on my bank and has asked them to stop debiting my account as they keep changing their references to debit. Each time I reverse the debit and take out the money out of my account it takes R105. From my bank. It accumulated over R1000 in one month and it's just ridiculous. Should I continue paying for products I have not received? I have not gotten feedback after Amukelani Matsala said that they would call me in 2-3 business days. This is *****.
