Reliance India Mobile — unfair closing the Sim

Address:

Jalgaon, Maharashtra

3 days ago i was using my reliance sim normally, than in the evening i called Coustomer care to repot my complain o[censored]nfair charge of money. one of the guy named Rajesh recived my call., when i was telling him my problem, he refuses to hear me, and started behaving as a child. then i just started replying in the same way he did. and at the end of the conversation he just said that he 'll show me smthing unpredictable within next 2 days. and the next day when i woke up they just bared my sim. taking a fake complait that i hav lost my SIM and i want to Block my SIM.
now it BARED.
how they can bared my SIM,
I have Paid for the SIM, it was not for free...
now according to them i hav to resubmit the whole Documents .... is this not a Harrasment for me..!!
why i'll resubmit the documents if it was their fault, who 'll pay for it.
Is this the way to behave Coustumers...??
