Pathetic or non existent customer service

On the 7th of June I placed an order for a pair of slippers and a pair of size 2 kids crocs. The items were bought as gifts for family members. Although delivery was delayed and only occurred after several phone calls to the office and the courier company a week later, the items were eventually delivered. However, the size 2 crocs shoes were an adults size 2 and hence incorrect. I again emailed Cherise, who apologized and referred my complaint to Zina. Zina rep**** via email, explaining that there was a glitch on their system and the crocs were incorrectly shown as kid's sizing but that she was trying to do a special order for me. <br> It has now been over 5 weeks since I initially placed my order and I am yet to hear from either Cherise or Zina. I have sent enquiry emails but I don't feel they think my complaint validates a response. I have also tried calling the helpline and each time the man on the line promises to call back with some feedback but never does.<br> This leaves me with a pair of shoes that are too big for the person I gifted them to and no means of refund or replacement, hence I have resorted to a formal complaint hoping this will initiate some response from them.
