Delivery and Exchange process via online store nightmare

I purchased a pair of loafers on line on Jan 21 at 11pm from a crocs mail promotion. At 7:30 the following morning I contacted the support desk as I realized I had ordered the wring size. I was told this was not possible but should wait for the delivery then go through the exchange process. This did not bode well Delivery was a nightmare with the courier arriving without any notification while I was out of town. Arranged delivered date came and went with no delivery. I then had to make a call to the courier to re schedule

I immediately completed the exchange form and submitted it . Then got a confirmation of receipt. Then silence. All mails to support go unanswered. No one takes a call at the support number. Redirecting the call to head office , after being on hold then told no one is available to take the call

At my wits end with them. Never again an online purchase from Crocs
