TFG / @Home Poor Service

I bought a Smeg Toaster at @Home less than 2 years ago and unfortunately it stopped working. I also unfortunately lost my receipt. When I enquired with TFG / @Home if they could provide me with a copy of my purchase / receipt, so that the warranty could be honoured, they could not assist me. How can TFG / @Home not pick up in their records that I purchased the Smeg toaster? I am now forced to pay for repairs. My own negligence in losing the receipt I guess, but surely with all the technology today, TFG / @Home should've been able to assist me with a copy of the purchase? Unbelievable...
