Terrible Service for such a high quality brand

Approximately four days ago my girlfriend bought me a R700 business shirt from Zara. She lost the slip at a gift wrapping store that day, however she was sure that the shirt would fit me. Today I fitted the shirt and to her shock it didn't fit me. I called Zara today to confirm that I could bring the shirt in to get a bigger size. Their reply was NO and that the only proof of purchase that anyone has of the sale is the customers receipt. This is the first clothing store that has declined me from exchanging an item without a slip. <br> Due to this poor service I will never buy another item from their brand ever again. <br> Zara should adopt a similar business model to smaller retail shops in the TFG such as Fabiani, GStar and Markhams. <br> <br> Regards,<br> A concerned ex-customer.
