Afri Mobile frustration

My partner have been struggling with communication and especially feedback on a query she lodged with Afrimob. According to her she cancelled the debit order with her bank and her bank confirmed that the debit order was cancelled. Three days later Afrimob again deducted an amount from her bank account. According to her she never signed any contract with Afrimob. She is very frustrated as she mentioned that she never gave Afrimob any permission and confirmation to deduct payments from her account. She mentioned that this has been a struggle for several months. She mentioned that no one ever responds to her queries or provide her with any feedback. She is absalutely devastated and frustrated and request Afrimob to respond to her as soon as possible.
