Short lifespan of a Pure Pleasure electric blanket

I purchased a Pure Pleasure king electric blanket from Game in August 2024 and when I arrived home I found it did not work. I immediately returned it to Game and received a replacement. In July this year the one control switch stopped working and soon the other one. Unfortunately I lost the slip and cannot claim a replacement again. I certainly will not replace it with another Pure Pleasure electric blanket as my problem seems to be a common cause of failure experienced by others as highlighted here.
