WRONG ORDER AND MISSING ITEMS

I HAVE ORDERED ITEMS AND I DID NOT RECEIVE EVERYTHING I HAVE TRIED TO COMPLAINT BUT THEIR NUMBERS RINGS WITH NO REPLY AND THEY DO NOT RESPOND TO THEIR WHATSUP MASSAGES , I HAVE REQUESTED THEM TO REFUND MY MONEY BUT THEY ARE NOT OF INTEREST

THIS IS THE 3RD TIME THAT I HAVE ORDERS ITS EITHER I RECEIVE WRONG ORDER , SMALL SIZE OR MISSING ITEMS

THEIR SERVISE IS VERY BAD
