Ultralink 4K Smart TV Box

On the 8th of July I ordered a Ultralink 4K Smart TV Box, they canceled it and claimed to be a system error, however I was not refunded as they say that the funds should automatically go back to my account. They told me to send a proof of payment knowing well I wont be able to retrieve it as they have not bank the transaction. Its been over a week now and they have not returned to me. Their number does not go through either. This company is a ****.
