Customer care sucks !

I would go below 1 if I could for the customer care ! I sent them several emails, just to be able to send stuff back that they too far to long to deliver : it took almost 3 weeks to get my parcel, but in the meantime we had bought something else. I then returned the goods.... Them wanting to deduct 15% handling fee PLUS postage paid by myself !!!!! Until today, nobody made contact with me (although they said they would on another review) about the refund and only now that I threatend them with a ***** case, they write to me that they cannot refund my money to my credit card.... with which I had PAID !!!!!!! This is so rediculous and bad and absolutely the worst service I have every come across in my life !!!!!!!
