I have noticed a couple of times now I get an email from Banggood saying. "Someone has asked a question about a product you ordered recently, can you help them?"
Now I'm a helpful sort of guy, so I thought at first this was quite a good idea. However, the first one I received, the question was "when will this item be back in stock?" Not a lot of point sending that to me.
Banggood, if you're going to do this, you have to either have a human first decide whether it's appropriate, or failing that, have some intelligence built into the system to filter out this sort of question. Otherwise it's just spam. So please either drop it entirely, or make it something I can opt out of, or fix it as I indicate above.
