Change my bill amount after 2 months on a year agreement

So is there a question? 

And if there is a question, please tell us specifically what service you're talking about and what your issue is.

Also note that this is primarily a consumer forum, we cannot see your account and you should not share personal information where it can be seen by the public.  The ATTHelp group are official AT&T Support reps, but they may or may not intervene in your issue.

I called in to get a lower plan and was given one for a year. two months later my plan was higher than what i was given for a year

You might get a discount for a year, but there is no price guarantee. Per increasing costs from networks, there is an annual price adjustment. Since it is January, it is quite possible the bill change is just that adjustment that happens once a year. To be sure, you would need to compare the prior bill to the current one.

If you were to share the line items of the bill, those in the community could help clarify if the annual price adjustment is what happened or something else. Otherwise, you will need to call AT&T as this is a public forum, not official support.

We'll gladly help you find out why your cost of service increased, annieje2.

In the future, you can visit the page on our website that covers how you can Find out why your bill changed.

So that we can take a look at your account to see what happened, let’s meet in a Direct Message. Please check your Direct Message Inbox (it’s the chat icon next to the bell icon in the upper right corner of the Forums).
