Tata Docomo — billing cheating

Address:

West Bengal

My husband bought tata photan for me in 2011 and later i gave it to my brother as i went back to bangalore. My brother is facing big issue with tata photan's cheating.

He closed the account last year march and reopened it last year may and then again closed last year november. whatever he closed it, tata photan claimed to pay more. for eg. my brother closed last nov and paid all due. this month tata photan sent legal notice to pay 1k. it happened 2-3 times. so how much do tata photan want more money from cheating my brother?

also my brother had receipt but that is made up of oil type paper which provided by tata photoan which printing become fade after some days. is that way how tata photan cheated us?

Please explain.
