Money transfer, virtual currency, or money service — Coinbase, Inc. (CA)

None. On XXXX/XXXX/XXXX i started a XXXX purchase with Coinbase. They cancelled my order on XXXX/XXXX/XXXX. They notified me saying i would get a refund to my bank account and it has been XXXX days. But i have not received the refund. I think they may have scammed me. I have sent them multiple emails and clearly stating my situation and i even tried contacting them on twitter with no luck.
