Poor customer service!

I wanted to make a payment well in advance before my debit order is due and asked that they cancel the debit order when the payment reflects. They are so useless that they cant even accommodate my simple request. The ******* excuse is that I agreed to a debit order so they refuse cancel the debit order even if I make a cash payment. Stupid company. Since they cant provide decent customer service I will not be using their credit facility in the future.
