Query about cheating

Sir,i was engaged with a boy few months back.They were told us and given a profile that he had MBA.But after the function we got a information that he only posses higher secondary education.Then we asked them to show us certificate.But they failed to do it.We waited few weeks and requested to kindly show it.But they were given the reasons like certificate were given in company.So we asked just show the softcopy,but they dont.So we decided to cancel the engagement.I am doing masters .During the engagement we were given them some cash and gold.They were told us they will give it back at the sametime they escaped and gone to saudi arabia.Then we contacted them and they told a date to give it back.But they failed to do.What are legal actions that i can charge on groom and his family?? How long it take to get back our cash if we go to court?
