MIDLAND MORONS took my payment out of THE WRONG ACCOUNT, not once mind you, TWICE!!!!

THAT'S DOUBLE THE PAYMENT I'M IN THE HOLE.
Yeah, I tried to work with
MIDLAND with my debt becuase
I LOST MY JOB. So not everyone has the same issues, like, not paying a cell phone bill becuase I was young and naive.
MIDLAND screwed up while I was trying to be responsible. PERIOD.
For payments, send a registered check or money order.
DO NOT pay over the phone with your own personal account number, credit card, etc... They have it on file. If they screw up, then unfortunately you get screwed also.

What should I do? Please and thank you.
