What should I ask for?

Remember the thread about my shaitel that somehow got ruined when I had it washed and set? So I stopped in to talk to them, but the woman who does the wigs wasn’t there, so I have to return. In the meantime, my mother spoke to the shaitel macher who sold me the wig, and she said if the person washing the wig puts too much cream rinse where the hair is tied it can make the hair come out! I’m terrified to wear the wig because the hair is falling out! So, I’m wondering, before I go back again, should I be asking for some kind of reimbursement? (I left a message for my rav, but he hasn’t called back yet).
