Unprofessional behaviour

To whom it may concern. <br> <br> I have a Woolworths loan and always pays the required amount. I am always up to date and I explained to the company several times that I do such payments via electronic transfer and that they need to cancel the debit order. However, they call me several times a day and then puts the phone down in my ear (at least 5 times every day). <br> At some stage I did talk to them and then they tell me the same story over and over \the debit order did not go through and that is the reason for our call". <br> What is going on?? The account is up to date and it is highly irritating and unprofessional for a company to call a customer every day just due to the debit order not running. Isn't it more important to make sure that accounts are paid and call a customer if this is not the case? <br> Thus"
