RCS / Makro Credit card

It all started when I visited Makro and they offered me a credit card. I accepted, but after a week I changed my mind and asked for a settlement. On the 23rd of March RCS send me a settlement letter which I paid in full and forwarded the proof of payment to ***. A month later I followed up but still no luck. They since handed me over to the attorneys, and I kept on escalating. They called me a few times where I told them to please read the notes on the system as I spoke to a few people and had a few emails going on.

Can someone please clear my account, close it and remove the listing from ITC
