It does not work. Again and again when I order something from Zalando I don't get any cash back although I always order on the lety page ... And when I want to send an invoice as an attachment, I only get it to my laptop. It doesn't work with a cell phone either ... Klompatt really ...
We are sorry that you had a negative experience with LetyShops :(
Didn't get order information from partners, but we'll try to find out why.
We see that you have already created several requests that are in progress. As soon as we get an answer from the shop, we will contact you :)
PS You can add invoice through your mobile browser to avoid using a laptop.
