Loan *****😡

I've paid the loan 5 months ago and I didn't apply for another one and 2 days ago, the debited the amount of R 3 500 and I needed that money to buy food for my kids and now the don't want to return my money. I spoke to Lebo Lesunyana, the owner of this company and she sounded as if she's not even interested to assist me and now she's ignoring my calls. I want my money today
