• What to do if I have been accused?

I was proposed my son’s marriage from Tatanagar with the daughter of Mr Nagendra Pandey around two months back. Mr Nagendra , his son and other family members along with the mediator visited my home at Howrah twice. We planned to organize a small ring ceremony function and finalized a date for the same that was  21st of April 2015 at Tatanagar.  We did our best to organize this ceremony. The function was conducted well. 
After the completion of this function we were planning to set a date for Tilak ,Marriage and Reception from our end while the other side Mr Pandey and their whole family started misbehaving  & talk negatively  with us on phone and the elder son of Mr Pandey and his wife totally refused for this marriage. We were hurt and disappointed due to their rude & changed behavior.
Anyways we again started a telephonic conversation to solve all the issues but we could not and the conflict started .  As we were hurt a lot we decided to stop this relation by their free consent on phone.
Now again a problem aroused when we simply asked them to return our jewelry and  other gifts and to bear the expenses  as in the ratio of fifty per cent (50%) of the both side genuine, true & authentic expenses but they refused our proposal . They wanted us to bear 100% of their expenses and they would not bear our expenses as they were blaming us we refused the marriage . 

Sir, 
As u know an arguments never ends on telephone so we invited many times for the  table discussion but all the time Mr Pandey ,His elder son Jay Prakash Pandey refused our proposal and started blaming us  and threatening us  on phone. They again started to claim for cash that is totally falls. It is True that they had gifted two bundle of rupees five hundred as in hand of our son as Neg (Shagun) at the time of pujan during the ring ceremony and they made a recording of the same intentionally to make wrong  allegations  on us if needed in future. Since beginning we were opposing to accept that because we don’t appreciate Dowry in any way but they convinced by telling that  they were doing only Shagun (Cheka/Neg) according to their will and consent. Anyhow we did not insulted them there by refusing their shagun because of our treaties and cultural etiquette.
Now they are threatening us on phone many times. They don’t want to come for the table discussion and for gentlemen talk while we have invited them lot of times for table discussion. They want us to pay Cash ( some time 1 lakh,some times 2 lacs& some times 2.5 lacs). Again they want us to bear the total loss and expenses. They are not willing to refund the ornaments and jewellery   which was gifted by us to them & those ornaments are precious to us because those are  souvenir of my Late Mother and my late Wife whom I lost last year to an unfortunate demise. My whole family has come to turmoil and no hope of ray is visible to us ….
