My skin color is red and I have brown spots three weeks after my peel. What can I do to correct this?

Three weeks after my peel, I am still red and I have dark spots where my skin first peeled, and then peeled again. I was supposed to have a microdermabrasion done two weeks after, but the spa I'm going to will not do the procedure because they still say I'm healing? At this point my skin is worse then when I went into this. My peel took two weeks. Peeled once and then a second time.
