roncor group inc. didnt pay anything on one bill, dont know if they paid anything on any of them glendale California

Back in 2016 I contacted roncor group inc. I heard the ad on a radio station. In August 2016 I started paying them via debit of my checking account $279 per month. In April of 2017 I get a letter from an account that they were supposed to be paying threating collection procedures, I contacted Mr. Padilla of roncor group inc. and was told to send the letter to them and they would take care of it. As of late may I was still getting letters and phone calls about this debt. I e-mailed roncor group and demanded that they send me a statement indicating to whom was paid and how much, I indicated if I didnt recieve this info within 7 business days I was going to cancel my contract with them, I never heard from them. In June I put a stoppage of the checks that were being sent to them and filed a complaint with the Attorney General of Arkansas. They were contacted by the AG and said they needed an address to send the refund to, that letter sent by the AG was dated July 7th. I emailed them my address for the refund, which they had anyway. i have not yet recieved anything from them. and found out today they havent paid 1-cent to the debt mentioned above.

I PAID THEM $279 for 10 months with my mastercard debit card
