In this task, You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.

[EX Q]: I placed order and was given delivery date. Two weeks after delivery date, and no magazine, I inquired and was told my order was received after offer expired.
[EX A]: negative

[EX Q]: I purchased in June and hired an HVAC professional to install. After several calls to Nest support, it was determined that we had a faulty plate so we attempted to install the 2nd and again after several calls and a couple of hours, determined that that one wouldn't hold its charge long enough to install. In both cases, the window to return them had lapsed so I am out of $400 plus and then had to buy a regular thermostat to boot! Lesson here, do not buy this product until you are ready to install it!
[EX A]: negative

[EX Q]: It works but you have to go to their poorly coded web page which seems to only record a weeks worth of data. It doesn't connect to any usefull services except a couple that you have to pay for. Regretting spending the money on a device that won't connect to my smart home. Worthless. Every time i try to add a service to push data to, it fails and says my meter is offline for hours to a day. Seems to be broken again. Guess I’ll send another support email in the morning. All my data is missing.
[EX A]:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
