Mumbai University — wrong information and delay in providing grade card

Address:

Kalina mumbai unversity ,lower parel, mumbai, Mumbai City, Maharashtra

This is a student of thakur college of commerce and science tybms (2018).
I gave my sem6 exam on april 2018 and unfortunately i got a kt in one subject (Operational research) and in october 2018 i gave the exam. On (2019) 22 feb online result was declared and i am successful. But its now almost one month and i have not yet recieved my kt marksheet. I visited mumbai univ more the 4 times they provide me wrong info and on 14 they told me to issue a letter from college and i did a hard work in it and made it from collge. And on 16 when i showed them the letter they told me that ill recieve it within 2 days and didnt recievd the letter but today its 19 and now they say its now not ready yet it will take time.
I am writing this complaint because of carelessness of mumbai univ. They have wasted my one whole year. R since i was applying for my futher studies in abroad and given all exms and evrything was ready but due the carelessness of mumbai univ officals i have a bad impact on my life now. Hope strict action must be taken against the officials.
