just saying dont be shocked to see these cancelled and your cash back
o and they do THROTTLE people on prepaid plans cause they know they can (since if you cancell you out all of the cash)
You are clearly not very savvy in economics/business.
If their customers are not satisfied, they will not renew after their prepaid ends. It is not smart for them to "throttle" those customers because they could lose potential future business and because word of mouth is such a big factor when it comes to online-based businesses.
Besides...any intelligent person would not use up all the gift card codes at once anyway. They would spread them out and use them when they needed to, only after their first card expired.
