Instruction: Given the user's review, identify the user's sentiment from the listed options. Answer using one of the options.

Input:
The battery received was not an APC battery.  I don't know if I am having a problem with the UPS or the battery, but according to the UPS's display, the battery is not taking a charge.  I gave this 3-stars because I'm giving them the benefit of the doubt that its the UPS that's faulty, not the battery.  But I'm not happy with the bait and switch that the battery received was not the APC battery described and illustrated.
