Debit order loaded twice this month

Companies have no respect for their clients anymore and PPS is no different. If I dare miss a payment you will probably immediately cancel my cover without a second thought. However when you make a mistake like debiting my account twice then I have to just accept it and now spend my time to get my money back from you after you incorrectly and *******ly debited my account twice. We have a legal agreement for you to take a certain amount by debit per month, anything you take above and beyond that is ******* as you are taking money from my personal account for which there is no agreement for. So to simply put it, it is *****ing. Fix your systems and reverse the debit order. It is unnacceptable for you to debit a clients account twice. There is no excuse for it. I don't care if you have system faults and issues, it is not my problem.
