Consumer Rights-Small Claims

I purchased a beauty procedure in Michigan, and it did not work, after submitting a complaint, the company agreed to issue me a full refund. After being given the run around, the told me I would receive it within 8-12 weeks, it's now been over 13 weeks, and they are now telling me an additional 1-2 weeks. I would like to now take them to small claims court and sue for the full refund, time I have spent pursuing this, statutory interest, as well as any court costs, and costs related to having them served. Is it likely that I will be reimbursed for the extra fees/costs if I proceed in small claims?
