Wumdrop useless

Ordered from Makro. Makro organsied delivery on the day of order. Collection from Wumdrop occured on day of delivery. 3 days later my order is sent back to Makro as "I wasnt available". No phone calls from them. No attempt to get my attention. Nothing. When I ask for a status via their website chat, I am told "Its sent back to store" and chat closed without any option to talk.
