Bad service( can't get hold of you)

I would suggest you do not buy from Little Owls on Facebook. I placed a order and paid for the product on the 6 December 2018. The invoice said it will be 10-15 days(not working days). I have contacted Marijke on Tuesday the 18 December. She told me she has my duvet inner she is still waiting for my duvet set. I have tried asked on Whatsapp every day where is my stuff. No answer and today I phoned and phoned and phoned even left messages on Facebook and emailed them.
