How bad are you at your job

<p>Dear Woolies. </p> <p>We have been through this again and again. I changed my bank details in September 2016. I have been paying my account every month and every time I had to send a proof of payment. But still you send me messages saying that my account is overdue. You get my interest wrong and make me pay more. I payed my account in full this month to close it, I send the proof of payment on the 15th of this month. And guess what? I just got a message stating that my account is overdue. Can you please do your job, this is just sad. </p>
