I second that. Data caps are not technically neccessary, that has been proven time and time again (especially March - June). They are pure greed by ISP's like Comcast. If I had a choice of ISP in my area, there would not be a cap. In regions where Comcast has real competition there is no cap. They can charge me $30 per month and get away with it, I have no choice. Shame on Comcast for misleading and ripping off consumers.
I just got a data cap limit warning .. but there is no mention of data cap in my contract.
If I get 1 more warning on my data cap or if I get charged for data cap, I will be going to another ISP as I don't want to pay $25/month to remove the cap. I would rather pay 1-time contract cancelation fees than a monthly 25/month or the $10/50gb upcharge.
Good luck. In my area I only have one choice, it's Xfinity or nothing. Comcast takes advantage of that with monopolistic behaviors such as data caps. I caved and was forced to pay.
