Hostel — allocated my bed to the other person and when questioned shouted on me.

Address:

500081

I am staying in sri nilaya pg, madhapur which is besides sri venkateshwara arts college, image hospitals road.
I have joined the pg on 7th of feb 2018 and i have informed the owner named sumathi that i might get a seat in mba college and might vacate the pg, clearly mentioned her that the results are not yet out but just giving you an intimation.
We had a discussion on 25th of may.
I got a call from this lady on 30th of may asking me to vacate the pg on 1st of june 2018 as she allocated my bed to someone else.. I spoke to her saying my date was till 7th and also at the same time i got my college results and the joining date is 18th of june so i will be paying on daily basis and stay till 15th.
She didn't accept my proposal and in return shouted on me.
I just asked her how can you allocate my bed to someone without informing me.. She mentioned its there pg and they can do whatever and they want.
I explained her my situation... I got an admission so will be having hectic work in office also.. I need to go to bank for applying loan and other stuff so it would be difficult to vacate hostel just for 7 more days that too when my advance was with you... And it would be difficult to search pg, pack and then unpack just for 7 days. She was not listening and made to speak to her husband as well who joined her in arguing and finally said they will return my advance and asked me to vacate on 7th of june.
I only have 2 issues now.
When i didn't mention that i am sure of vacating then she should at-least call me when she is allocating my bed to someone.. But she didn't..
My second thing is.. I am paying her money.. Not just staying here for free.. So she don't have a right to shout on me..
In all the things going on my mind about office work.. Loan matter.. College start date is approaching and all this incident made me sob and when my roommates asked i explained them in detail.
They also mentioned that there are many such incidents going on in this pg.
Please take necessary actions so that they won't repeat this again.
