Unfortunately, I was scammed by Tecnauto, an order of more than 60, 000 EUR on car parts.
First we had quick replies on emails until we sent them the payment by bank wire.
After more than one month, we asked them for the parts and they start being upset and canceled the order.
Now they don't reply anymore and didn't send the parts or refund.
This is the common procedure on companies from Mr. Nuno and Mr Joao (now we have checked reviews on these companies).
