Internet data and grace period

I thought it odd they told us "not to worry" when they "increased" the data cap from 250Gb to 600Gb "as most customers never use that much data." Now the first month I've magically used 750Gb after never going above the previous data cap with the same habits. This is very sketchy on At&t's part. I'm less than half way into my cycle now and I've blown by the 250GB data mark again (after not ever breaching this the prior 7 years I've been an AT&T customer). Just got back from vacation and during the days we were away we "magically" used 7Gb worth of data. This is sketchy and I don't like it AT&T. Wifi is a utility not something you should be nickel and diming your customers about. Not to mention its not like you've improved the service at all. Why start with this "overage charge" crap now???

Mine was increased from 250 to 300. 1st month no problem in fact told kids to use a lot. Second month exceeded and did nothing different.. AT&T is dishonest on many levels and there is something very sketchy about this. This needs to looked into..

I have been checking it out ever since I got my Router configured to measure all traffic flowing through my Router's WAN port.  For the period from 6/27 through today (current billing cycle):

 

	AT&T	WRT-Merlin	%off
Total GB Downloaded	336.31	335.68	0%
Total GB Uploaded	13.98	12.85	9%
Total GB	350.29	348.53	1%

 

The previous verification I did (6/2 through 6/15) was even closer.  I can compare each day, which vary in how close because my router separates the days at Midnight EDT, or 4 AM GMT, whereas AT&T cuts the days off at Midnight GMT (or 8 PM EDT).

 

I did not think I was using this much data.  I still don't think I am, but my kids are doing a bunch of HD streaming (to tiny phone screens... I mean, what's the point? Why not SD?).  The Router software shows IP by IP utilization and I see where it's going on a per-device basis.  Tells me mountains.
