Sounds like a bodyshop car to me. I've never been in that situation, but it's common on fault claims to just be given the cheapest thing ever (hyundai matrix is so far may worst!)
See what MB customer services come back with, have you owned the car from new and had the servicing done at dealer?
Also interested why it could be up to a month!
