Rented property without aggrement all dealings in cash no reciept.

Used to live in a flat rent was 21000 with security of the same.no aggrement done. Only filled the tennent verification form which wasnt submitted to police as we took possesion. A year after we asked to leave the flat.(group of 5 friends were staying).the owner said that you have to give me the rent also and then we asked that the last month rent will be adjusted in security she said no i want rent and then uske baad jo cut karna hoga we will do it. We knew that we will loose the whole amount bceause we were promised many things while we were taking the flat but none was done as the condition was not good so we got scared of loosing money and we left without telling her and created a story that we all had a fight and no one talks with another 4-5 months passed and now we are getting calls by a inspector telling us that i can issue a search warrent but i dont want to spoil your carreer and is asking us to come because she is having a source of a high level police person. And now the allegations are about we stole the ac and gysers and tubelights everything but the truth is the only thing pending is the electricty bill and water bill which amount to 24000 in which half of the security be adjusted so the remaing amount is 12k-13k and the accused amount is of 40k-50k.what can be done. Should we not answer the phone or not because any how we just want this thing to get stalled till may then we all will be out of chandigarh. What should we do
