OK so he answered you.Hi, the invoice was paid on 9-4-21, his last message was on 10-4-21
I have mailed him on his email adress that's on the invoice on 19-4-21 , asking him what the status was and if there was any problem that i could have a refund
He did answered me after that mail on the same day, he told me that he would provide more info when the laser was done, (wich i found strange that you couldn't give any information after 9 days)
Then i asked him on the same day what kind of material the laser would be and that's it's possible to have it made in brass or stainless steel
Now we are 4 days later and still didn't answered back
What do want from anyone on LPF about someone not answering another email question you sent to them?
Either he does or does not answer it--deal with it.
Not sure why you are posting every step of a simple purchase transaction on LPF.
Are you either a child or someone who has never purchased anything over the internet or with PayPal before. maybe?
Nobody on LPF has any say in or anything to do with your purchase however it takes place/progresses or doesn't.
Ask him when is it going to be finished and shipped. Ask for an estimated time of delivery/shipping, completion of the laser and shipping date, which you should have done before paying and leaving the time frame open ended and whenever he gets to it.
If he already started mating the host or assembling the laser it s probably not possible to change the host material.
Can't have it both ways hurry up make and ship and also change the order to something different. Common sense.
You can always ask to cancel the order and get a refund if he has not started to build--ask him if he has started the work it that is what you want to do.
See post #7 here where he says "20-30 days after pay ,i will fnish" may be typical time frame if he is making something not in stock for an order: https://laserpointerforums.com/threads/some-my-host-and-my-build-in-this-time.107110/#post-1585697
