The worst service Ever

I paid off all my debt a more than a month ago. I sent paid up letters to Debt Rescue so they can send me my clearances certificate. Everyday I receive an email from different people asking me things given to to them and today Lindiwe emailed me asking me to increase my payment. What payment? I have never experienced such bad service it’s like they making it a point to make my life hell. All I keep asking is for CC. No one takes complaints seriously. Worst mistake of my life going with them. It’s caused more headache and stress. They even called to pay one of my vendors! I have had it. Going to complain on all channels I can cause no one is helping me. Do not go with them.
