Looks like there is some inconsistency in how they're handling these.

To date, my experience has been that if the system or *777# tells you that your airtime balance expires on the 20th, that you have until the end of the day on the 20th to refill.

But last month, my MediaNet features package said the 20th. When I went to refill on the morning of the 20th, it had already been wiped out. I called CS and they gave me a "one time" credit and reestablished my balance. They told me that the date is the wipe out date and that I had to refill by the day prior (the 19th).

I listened closely to the automated message and it does say something like "which you can use before October 20th". I suppose the 19th *is* before then. It's very literal.

Anyone else experience the same thing? I haven't bothered calculating whether or not I'm actually getting 29 or 30 days with the feature packages, but the inconsistency of the terms/system bugs me. I set calendar reminders for the expirations and it'd be easily to forget and mess this up. Now that the OLAM allows for automatic feature package renewal, has anyone checked to see if it sets the correct date? Or is it up to you to set the date?

Hope this prevents someone from the same surprise that I got.

The date of the refill counts as day one. Only unlimited data plans refill the day after the old plan expires. So if you add a limited plan to another limited plan, you increase your allowance on the day you add it.

Thank you for your reply and from reading some of your other posts I gather that you're an AT&T Wireless employee. You've shown that you're willing to help and I'm appreciative.

You didn't, however, address the primary point of my post: that the info given by the automated systems are inconsistent for airtime and feature expirations. The date given for airtime seems to be the final date of actual use before expiration. The date given for features is the day after the last usable date.

Can someone confirm this?

I won't go so far as to say that the information provided by AT&T is misleading, since "[your features] which you can use before XXX date" is unambiguous. But "your airtime expires on XXX date" can be ambiguous. When on XXX? From my experiences, it expires at the end of that day. But it's not entirely clear.

As for your contention re: the math and counting of days, the point is that people do not expect to have to count themselves. They will go by the date(s) provided. As a test, though, I logged in and looked at my account history.

I last refilled my MediaNet on 9/18/2009. By your information, that's Day 1. OK, fine. I put that in Cell A1 in Excel. The automated AT&T system tells me that I can use it before 9/17/2009. Based on prior experience, I really need to refill on 9/16. Guess what? Cell A30 in Excel is 9/17.

I would have never bothered testing it without your post, but it looks like AT&T is only giving me 29 days and not 30.

Buyer beware. They're skimming a day from you on feature packages.

refill for data due on 10/29- set up auto refill they set it up for 10/30. ? Then they sent a text data for renewal was 10/29 ???
