Poor show, Zara SA.

So very disappointed in Zara SA. I returned an item about a week later than their 30 day policy allows because I had been travelling. My request was to exchange the item for the exact same item of a different colour. All tags were in tact and I produced the till slip. However, they were completely unwilling to budge. I cannot understand any reasonable rationale for this. It would have been useful if someone could have explained - rather than just spew out their "policy". I would have expected a much higher level of customer focus and care.
