poor customer service

Never have i ever received such bad customer service. It all started with There is no level of professionalism at all . We have an agreement as to which bank they need to debit from . To my surprise they went to debit the wrong bank account. Basically they double debited me. On the account that they not supposed to be debiting from and the account I have an agreement with them on . The inconvenience I experience. My bank charges this had cost me, are they paying for them NO! who gave them the permission to go and debit the incorrect account ? I need answers not attitude combined with bad customer service ? With all of this being sad, I was once advised that should I refer a client to them i will get commission. I referred my sister to them and when i enquired about the commission the area manager was busy telling me something that i was communicated to me by the store consultant . Why is the store communication misleading? Could there be a problem with the training ? I want answers and I want this to be resolved ASAP. I will also be escalating this to the OMBUDMAN
