Complete Lack of Customer Service

I was contacted by Johnathan from MFC regarding a debit order that was returned unpaid. This specific DO is for the 15th. I have 6 vehicles financed with MFC and the others are all for the 30th. Johnathan was extremely rude and spoke down to me. When i asked to change the DO to the 30th, he said i would have to pay a fee, but said he could not tell me what the fee would be, it could be anything. I asked how he could expect me to agree to pay an amount when he couldn't tell me what that amount would be. He was arrogant, stating that i owe them money and that i can't change the DO date to the 30th. I asked to speak to his supervisor so he hung up on me. MFC, i will make it my mission to settle the 6 accounts i have with you as soon as possible and i will not do business with you again. Not if this is how you deal with customers. I am disgusted.
