I am handicapped. Prather's services started remodeling my bathroom 6/11 and as of today, they are still not done. They were misleading about getting my vanity. They installed a shower bench that I can’t use. They improperly installed my sink. Now they want me to pay $3500 to fix their mistakes. This is an extreme problem for me. I haven’t had a working bathroom for two months. Can you help me with this?
