Machine Zone Game of War Fire Age Refuses to Refund for their mistakes Palo Alto California

Yesterday I purchased a $99 pack from the Game of War Fire Age app that I use. I selected the level 23 pack and proceeded with my purchase. After purchasing the pack I went into my reports and found out they gave me the wrong pack. I immediately wrote an email explaining the.mix up and asked them to fix it. I waited four hours with no response. I wrote three more emails and then they finally responded. They said that they will not refund me the money and will not do an exchange. I immediately wrote them that I had spent specifically wanted the level 23 pack and not the one they gave me. I told them that I did not use any of the stuff that came I the pack they sent as well. They never wrote me back. I called Google Play store and explained the situation to them and they looked over the purchase and asked me what happened. After explaining everything to them, they said they will try their best to refund the purchase. After about 15 minutes, they told me that they were not able to and send me paperwork to fill out and send to the developer. I was told to also try calling my card company to see if they can get a refund on the purchase. Google told me that they will make a notation in their files to see if there were other reports like this and that they'll file a report against Machine Zone on players behalf if it see a pattern. I called American Express and explained the situation them. American Express loked through the purchase. They told me that the payment was processed but if they money was not returned by the 17th, they will also file a claim against Machine Zone as well. They gave me a set of paperwork via email to fill out as well to send to the developer. Now I will not be able to participate in the kingdom versus kingdom events, build my accounts up (I have 3 total that I spend at least $300 on each) and protect my investments. This is not the way a company that makes billions off their users should treat us.
