StraightTalk Overcharged my card Nationwide

Last year, I decided to go to straighttalk instead of verizon for the savings.  I purchased one year of unlimited service and all went fine until it was time, this year to purchase another year's service.  I logged onto their website, purchased the 1 year of unlimited service for a total of $546.73 with my debit card.  As is the normal course, straight talk a hold for the amount on my back account.  Only they did it three times.  I called Straigh Talk and thought I had explained to the CS rep what the problem was and that I needed them to release the two extra holds for $546.73 they  put on my account.  

She said, "check account 24 hour."  24 hours later I check my bank account.  They have subtracted $546.73 twice from my account and still had a hold on another $546.73.  So I, LIVID, called straight talk again.   This time they try to tell me it will take 2 billing cycles to refund my money.  OH, HELL TO THE NO!    Finally, after much demanding, I get a Real Supervisor on the phone who tries to tell me I have to have my bank dispute the charges.  

Oh, Double HELL TO THE NO!   No way I'm having my bank dispute the charges over a mistake Straight Talk made costing me over $1000.00 which, at this point, they basically stole from my account.  And they want me to have my bank dispute the charges?   Why in the world does Straight talk not hire 1) ENGLISH speaking CS Reps,  2) People who understand basic concepts like, "You over charged me. Give me my money back?"
