Bad Service

I purchased a top from Zara Sandton City last week Saturday. I had no reason to keep my slip as I tried the item in store and was happy with it.

Last night I wanted to wear it for the first time and noticed a tear on the inside of the top. I went today to Sandton City to ask for an exchange.

The manager said that he will not return without a slip. I said I would show him the purchase of my item on my banking statement and surely he keeps track of what is sold in store. He said he has no way of knowing what is sold except for the customers slip? How then does he manage his stock?
