I made the mistake of getting the DT spec Helmet and after all the failed timelines I tried refunding. It ended up being me doing a charge-back through my CC because they failed to meet their own allotted time they gave me for processing the refund, took screen shots of the chat logs with them as proof to the CC and they gave me back all of it.
I'm curious about the chat logs you mentioned. The only thing i could find was the send a single message button. Is that what you are referring to? I'm curious as I'd like to try that before I go the route of going to my bank with a chargeback. I had even thought if the return was handled promptly I might feel inclined to give them another shot.
Thanks
