1 of 5 Never received my order August 8, 2020
Reviewer: Jennifer F from Las Vegas, NV United States  
My order was promised to arrive by July 31st. As of August 7th, it still has not arrived and my attempts to get help have gone unanswered, aside for a link to review the items in the order I never received and USPS has no record of it since it was in Georgia on August 1st. Nowhere near me in Nevada. I guess I'll have to dispute the charge with my credit card and find a reliable source for the batteries I need. Incredibly disappointing customer service, or lack thereof.
