Not answering complaints

<p>On 4th April 2017 I contacted standard bank card division to get my outstanding balance on my credit card. After being transferred a couple of times, I came to a lady who helped me. The amount was given to and I paid this amount in the next 5min. A month later I get a letter from a unknown debt collector stating that I have an outstanding balance?</p> <p>I have contacted card division on the 24th May and 31st May. I contacted then the normal helpline, they forward my quiry to them as well. It's been over 3 weeks and no one even bothered replying back to me. I'm trying to resolve this, and standard bank doesn't care!!! Please check my phone conversation with you around 08:15 my local time 09:15 by you. Best is to see when i did the last payment and look around 5 minute before that.. or you can look who accessed my account on that day. </p> <p> </p> <p>Standard banking stating that they will reply in 48 hours!! they are quickly to claim things back from you and send you snotty emails . But actualy to go check what happened because now I don't owe them anything... they just don't bother. </p>
