Spot on Blaster. Any CREDIBLE e-Tailer would be more likely to respond in this fashion . . .
Customer: I received my purchase and there is a problem with the product. Here is a description and pictures to highlight the issue.
Vendor: We are very sorry this happened to you. Naturally, things like this can happen from time to time, but we are anxious to make this right, as we value your trust. Please return the defective material to us at our expense, so that we can address this with our supplier. In the meantime, we would like to reship your order, or something of similar value, if that is something you would prefer. Please let us know, as your satisfaction with our service is of the highest priority to us.
An exchange of that nature is what a Customer should expect. Anything else is just stalling and delaying in the hopes you will give up and go away. Preferably without raising red flags for their other Customers.
