So the reason they requested the pictures is because of the reported issue.  Its standard practice to ask for these items when a potential saftey issue is reported.  However, that said its not required.  If you do have the means to provide this information all you need to do is let the agent know, which it looks like you did as they have moved on to vlaidating the purchase to approve a replacement.  All you need to do is respond to that email with a copy of your proof of purchase and the process can move on from there.

Sorry Carl - if that were only true.

First I get:  To begin the replacement process we must first validate your product.  Please provide an image of the receipt or purchase order along with a picture of the label at the bottom of the product. 

Second (3 hours later) I get:  To begin the replacement process we must first validate your product.  Please provide a picture of the sticker label at the bottom of the product. 

Never mind I do not own a phone-camera or regular camera, which I've repeated so many times I really wonder if there is an English problem, or a Comprehension problem.

I am going to try and scan it in.....really....Scan A Router - What a joke!

And I am willing bet, before the day is out, they'll want something else, from a camera No Less, before "the next step."  What a reaally unfortunate operation this is turning out to be.

So, no.  Its not just a case of send in proof of purchase.  Its a case of sending in Multiple documents, over time, and to what end - who knows !!!!

Honestly support is only asking for all of this information as a time saver to know if they can approve an RMA or not.  all you need to do is register the product on https://myproducts.tp-link.com/us/login?redirect=%2F.  Now you will need to provide a copy of the proof of purchase.  This is so we can validate the purchase and ensure the seller is authorized.  Products sold by unauthorized retailer/re-sellers are not eligible for replacements.  sellers on marketplaces such as eBay or Amazon's marketplace are typically 2nd hand sellers and warranties cannot be extended.  What you can do is also email ussupportteam@tp-link.com after the product is registered and our local support team can review and approve the RMA should the seller be authorized.  We don't need pictures sent the POP can be put in the warrant system when you register the product.
