Builders aids and abets ************ manufacturers warranty claims

I purchased a very expensive Aurora LED globe on the 16 April 2016. At the time Builders/Aurora were running a special promotion. Purchase their globe with thousands hours warranty (i think it was 10 000 hours, which equates 2500 days if the globe is on for 4 hours a day or almost 7 years of use). At the time I interrogated the claim as there were competing cheaper LED globes for sale. The salesman assured me that these could be returned an replaced if it didn't make the 10000 hour cut. When an Aurora globe went out (say 1100 days about 89% short of their supposed guarantee life), I went back to Builders to claim on my warranty. Sir, we can not replace this globe as you need to produce the original slip. Here is my issue and my warning to consumers - these fancy claims are not worth the paper they are written on. Builders in aiding and abetting Aurora, take the consumer for a ride as they work on the principle that you are unlikely to keep a till slip for something as small as a globe. They have no intention of honouring these claims. The globe distinctly has a code printed on it, which I don't doubt for a second could easily pull up the batch and date when the globe was manufactured. While this is a little thing, it certainly speaks volumes about Builders and Aurora's integrity.
