I bought a pair of dumbbells from a seller. The photo was very misleading and presented them as a pair of **lb. dumbbells (which is what I wanted). I realized less than a minute after I paid for them with my credit card that in tiny print it said it was actually two *.* lb. dumbbells. I was already chatting with the seller, so I immediately let him know that I didn't want these and would like him to cancel the sale. (Also, the cost was not appropriate for dumbbells of that size.). After replying to all my other chats, he went silent. **I have sent a report to OfferUp via email. Super frustrating that there's no phone number to call when things like this happen. Will they do anything? I don't know. I also contacted my credit card company, who said I need to wait until the transaction posts to dispute the charge. **Is there anything else I can do? I do not want to pay over $** for *.* lb. weights that I don't need!!!! '**Thank you for any assistance you may be able to provide.
