Dim display on controls

I bought this blanket for my parents. While they both loved the plush feeling of the blanket, the controllers are so dim you can barely see the numbers. This was a huge issue for my mom, who has intermittent double vision due to Parkinson's Disease. Even I had trouble with the display, and I have good vision. I called the manufacturer to get replacement controls but they said this is a known issue and they have no estimated fix date, and to return the blanket to the seller. Very disappointed.
