Ok so i found this on their website...
You may terminate service for any reason within 30 days of activation. If you purchased a wireless device from us at a promotional price at the time of activation, you must return that wireless device to avoid being assessed an Early Termination Fee of $175, or $350 if you purchased an Advanced Device. You will remain responsible for your Activation Fee unless you terminate service within three days of activation. You will also be responsible for all applicable usage fees, prorated access charges, taxes, surcharges or other charges that accrued to your account through the termination date. If you paid a security deposit, it may take between 30 and 60 days to process the return of your security deposit. The charges for any service used on the account before the service termination date may be applied against your security deposit.
I'm sorta confused i can only cancel withen 3 day's without being charged or the 30 days?
