Air Arabia — Bad loss of my baggage

I have an issue... I would like to be resolved as soon as possible of bad loss of my baggage... That is almost 30kg
In 19 of july 2017... From sharjah to khartoum... Flight no g90667... Class y... Gate 3... Boarding time 2105... Seat 26b... I traveled from sharjah directly with no connection to sudan.. And when i reached there... My baggage didn't show up... I complained immediately at the airport to the staff... And in i waited for the next fly and the one after it... Then i came the other day... There is no trace of my baggage... I keep coming the next 8 days... But unfortunately my back wasn't there... I called the office of air arabia in sudan khartoum... One time they told me my baggage in sharjah... The other days they told my baggage traveled with me in the same flight...in 9 days i have nothing to wear no money and my questionnaire of my research can't not be completed without this paper... And am running out of time... I have my medication for epilepsy for 3 months... Beside my very expensive clothes and my perfumees creams accessories including gold... And i can't wait no more... Last year i had semilar issues with air arabia i paid my ticket and when i came to the airport they told me the plane is full and we can't let u in... And they promise to stay in hotel 5 stars... And room by my self till the next fly... And i agreed then the room was consist of 6 beds not comfortable to sleep in... I travelled different air ways without any this type of issue... This is how air arabia is treating their customers.. Because of some unprofessional staff airline... Spoiling their brand value and losing there customers... Requesting to take some serious action or unfortunately i have to deal with this in law... And definitely you lose me and all my family and my friends as customers... I want my baggage as soon as possible...
