I order ISO ELM Interface from digimoto
I pay an extra for shipping with tracking number.. (btw faster.. 5 days)
I pay on may 20... (i receive mail from digimoto.. they have receive my order)
on may 24.. I send email to know when my order will be shipped (because i receive no tracking number yet)

today.. it's may 27 ... no answer from last email.. no tracking number.. no parcel..

before to send my order.. I asked some questions by email and i received quick answer.. (always same day)..

is it usual with this company ?
