False advertising and incorrect supplying of lipo batteries

Ordered and paid for a ge power 1500 mah lipo. Recieved a 1200 mah lipo. Contacted Henry and he notified me that the price is loaded wrong on the adverti*****t and the price I paid was for the 1200mah lipo and that is what he sent. This is not right and he advised that I can send the lipo back for a refund. If I new this would be the case I would never have ordered from them. I have all the mails as confirmation. I also have a screenshot of original add with pricing. Not Happy
