<prompt> Human: Hello Reddit,Im very new and this is my first post.I was wondering what I should do about my roommate overcharging me.I live in Los Angeles and I just found out our electricity bill is Bi-Monthly and not monthly.I asked my buildings resident services as well as Los Angeles Water and Power, they both confirmed the bill is bi-monthly.So, heres my problem.Ive always thought our electric bill was high but Ive never questioned it because she sends me a screenshot of the amount total due.Shes been charging me every month for 8 month, 100-300 every time. Shes sent me screenshots of the bill but Ive just noticed she doesnt include the dates.The electric company wont release any information to me as its under her name...and shes refusing to let me login to her electric account and claims she doesnt have any of the past paper statements.I have proof on a money transferring app of the amount Ive been paying every month for electricty.What are my options?Thank you for any advice in advance.  <response>: Tell that hoe you want your money back
