I bought a Western Digital My Book 1tb external hard drive recently from Komplett.ie and it was dead on arrival.
I checked the Komplett site and was led to a page with instructions on returns

I followed the instructions and received an RMA several days later. I posted back the drive and a week later I received an email saying:
RMA item received, not tested yet.
You will be notified later by e-mail at the next action.
They haven’t even looked at it yet? AAaaaaaaaahhhhhhhhhhh!!!!!!!!!
This was on November 30th. I ordered this device on November 2nd. I still don’t have an external storage option over a month later.
Over the weekend I started looking into my rights as a consumer and I noticed on the Consumer’ Association of Ireland website that:
When you buy goods from a retailer, you make a contract with him. He agrees to provide certain goods to you for a certain price. If your purchase turns out to be faulty, the retailer, not the manufacturer, is responsible to you and must sort out your complaint. You are entitled to a refund, a replacement or a repair.
[emphasis added]
A refund? I didn’t see any mention of this anywhere on the Komplett website but according to the Consumer’s Association, I am within my rights to ask for it – excellent!
I have now emailed Komplett asking for a full refund. It will be interesting to see their response (and how long it takes). I’m not holding my breath.
