<prompt> Human: Just got an incorrect bill for over 500.00 from an ex-cableinternet company nearly a month after I cancelled with them and moved, due to them not processing my returned equipment. Its probably common knowledge not to do this, but I had always set them up to take the total amount every month and set no-limit as my bill fluctuated slightly due to bonusespromotions activating and expiring.If they dont have an option to limit the payment amount, spend the extra 2-5 minutes to read your bill, understand it, and then pay it through online or by CC. It could have put me in a real bind if I wasnt financially prepared or if I was a student, etc.This may only be applicable in Canada, Im not sure.  <response>: Long story short but Sprint screwed up and managed to take 2600 from my account, and just like any other business..they want their money immediately but repayment takes 4-6 business weeks.
