Good Feet Store — Arch supports

My wife was told by her doctor that she had high arches. She was having pain on the right side of her foot. High arches the doctor said was the cause.
We went to the good feet store and ask how much the arch supports were. The sales lady said about $300, it's a 3 support system. Well that's $300 per support total $900 plus the shoes over $ 1, 000. 00
Her foot still hurts and now she has pain in her hip.
May have to call an attorney because they don't give refunds.
