Making emty promises?

We bought a second yoco card reader with the promise that the beta version of the product upload file would work, and as it has been made available to us i would hope that help would be given if issues are found. for the last 2 days we have been struggling and no real help, the online chat just indicates that its beta and no support..but that is unacceptable. this is a basic db upload, so if the front end does not work yet, surely a tech person can just upload it in the background for us? we have a market this weekend with over 300 products to update for 2 yoco's help is really needed???

Please contact wife Janine ********** or myself Dylan **********
