I ordered 3 items from Wilkos. The parcel arrived today, was open and only 2 items werer in it.
I chatted to Hermes who delivered it, but on the chat was only some bot who told me to contact Wilkos, who only had the option of some on their website email, and it said they would get back to me in 7 days! WTF!? This is just such crap customer "service" 
Just wanted to warn others. Also not quite sure what to do now, since they dont seem to be bothered.
