<prompt> Human: Im an idiot. Despite being quite good at being frugal and investing in the last year, Im still given to occasional idiotic mistakes.I just got covered under my companys health insurance, and got vision insurance. Went to the eye doctors office and somehow got talked into spending 300 on designer glasses. I usually buy the 35 ones from Zenni. Had store immediate buyers remorse, called the office and they said they couldnt refund them, as theyve already been made.I can pay for these, but I wont be saving anything this month, and Ill probably have a little bit leftover that Ill still need to pay off next month.My Mom recommended disputing the charge through my credit card company. How much would this hurt my credit asks how unethical would it be? TL;DR: Idiot with new health insurance spent too much on glasses, regrets it, cant get refund. Any hope for him aside from being a not-idiot in the future?  <response>: Consider it a stupid tax and learn from it. On what grounds do you think you can dispute it?
