I placed the order not knowing that when you do the system automatically takes you to the size available. I was under the impression that I chose the correct size (3.5) and would receive my size but upon my surprise I did not .I have contacted Birkenstock in Cape Town on numerous occasions and been advised that I will be contacted and they will email me .Too date nothing .Very disappointed at the service as I have not received any feedback regarding my purchase and my options. I have emailed as well and no feedback.
