"...If your bag is delayed on your return home, airlines may consider that your losses were less as you had clothes and other essentials available to you....."
(edit for this link) And from Air Mauritius:
"....With respect to delay, carrier shall be under no liability except as provided in these conditions of carriage...."
You say that you flew back, so I assume you are home with all necessities (minus some clothing and toiletries), so not real damage (imo).
It's all a question of how much are you willing to spend on this issue in regards to what you would/could gain.
I would contact the airline (and/or airport) and make a claim and wait it out; if you get something good, if not, count yourself luck to have all your belonging back.
