I did this once, the advice I received was

"If you are using a browser that logs your history then find the order page at transaxe.com in your history > click on the Order ID > log in.

Or message Transaxe Support through the link i attached, send them the Bitcoin address you sent your Bitcoin to and they'll help."

I don't have the link though, sorry.

I also messaged the seller, eventually I guess the seller must've done something for me as the next day the order appeared in my account.

Don’t panic. Message help bot with you payment numbers and they can give you your order number. Takes a couple of days. Most will just send anyway and should confirm if you message them directly. Done this myself…

I done it myself mate I messaged the vendor and he said he had my order

If you can navigate back to your order on your browser you can log in on the order page and link it to your account.

Do you think I can ask for a refund on the order from the refund bot? I have the wallet address

At least one of my sellers has said they have sent it so fingers crossed it all turns up!

Oh no! I’ve messaged both the sellers and haven’t had a response yet!
