ZARA SHOCKING CUSTOMER SERVICE

I received a gift from gateway Zara via the post. I currently live in Johannesburg. I went to Zara Sandton on the 07 May to exchange for a smaller size. A member of staff informed me that I would need the gift certificate or A COPY OF THE GIFT CERTIFICATE and they can exchange it for me. I informed the staff member that 08 May is would be exactly 30 days since purchase but I was insured it will not be a problem. The staff member kept aside the Jacket for me to collect the next day. I Arrived next day to be informed that I needed the actual gift slip and they do not accept a copy of it and was told that its within 30 days so unfortunately there is nothing they can do about it and refused to help me or accommodate me. I was given a card with the customer service email address if I have any complaints and was told to take it up with head office if I have any issues. Poor customer service and not a scratch of help from your staff members. Staff just didn't have the time to hear myside of the story nor help me out. all hear from Customer Service is policy and procedure needs to be followed.
