AFLAC Dental PLan Falsely withdrew money from my account when they had been paid Columbus Georgia

I had dental insurance with Aflac I sat if up for auto with draw, in the month of June, I called them 

directly to pay my monthly fee. Within a few days they withdrew another payment, I did not authority

them to do that, they had been paid. I requested for AFLAC to return my payment, what they did was an insult

to me, they sent me part of the payment, what I did was return the check back to them and requested

again they send the full amount which they had no business touching in the first place, this was stealing

and what they did was wrong.
