HORRIBLE AND UNPROFESSIONAL BEHAVIOUR

I have an overdue account with Van Ci cash loans which i have not disputed and want to settle it however the lady i am communicating with on their Whatsapp platform is very rude to say the least her name is Wisani Mathe. I would like to pay my account via an EFT, but she is insisting on a debit order which i cannot do at the moment. I mean EFT is also another payment method why is it difficult to pay via an EFT ?
