Already working for 6 weeks on a solution for a (partially) incorrectly delivered product. Although I have clearly indicated (based on an earlier order) what I would like, I was not told in advance that the product (according to direct, on behalf of the supplier) in this form is no longer available. After some investigation, it appears that another online shop can simply order and deliver this!
The response from via direct is invariably; "we are waiting for a response from our supplier" or "our supplier says ..."
Best via direct, I ordered from you, not from your supplier. Come up with a solution yourself or be open to a solution from your customer instead of letting the customer wait that long.
And if you hit the table once in a while, the response is rude and scornful!
Recommended? So no...
