Query: Haier TST240SS toaster

I purchased this toaster as a Christmas present in 2010. Recently, the toaster "exploded" with an electrical arc shooting out from the end that is pushed for starting toaster. The owners contacted Haier about the issue and were told that "yes, there is a danger of electrical malfunction." The owners were instructed to fill out paperwork and return the toaster and they would receive a replacement toaster. However, Haier has no toasters available and instead sent a check for $21 which was less than half of the original price of the toaster. I would think that since they are aware of the electrical danger, they would at least refund the entire purchase price. They were very fortunate that there were no injuries which resulted from the malfunction. Quite a serious problem, I would say.
