I ordered online, but made a mistake on the delivery address. Despite me emailing them the same day and phoning them in the morning, I got no reply to my messages The phone line is just a message taking service but despite them promising to pass on the message and get someone to call back, no one did, despite me calling 4 times When I called again and asked for a complaints contact they refused And then they just sent me a terse email saying the parcel had been dispatched and they couldn’t change the address and had the nerve to add “Enjoy experimenting with Knoopology at home.” I don’t know about their chocolate but their customer service is dreadful. If they’d replied to my phone messages as promised they could have changed the address in time 14/05 I’ve upgraded from 1 star to 4 stars because after I complained they did switch up a gear and sent me a new parcel. Plus the chocolate is lovely!
