Visit Visa cancellation - Consumer Complaint for Seven Sky Tourism

I had got Visit Visa issued from Seven Sky Tourism in Feb’18 for my father and he entered UAE on 13 feb’18. On 7th april’18 i lost my father in Dubai. All the retiuals were done from Sharjah and his passport was cancelled by the Indian embassy which is in Dubai. I was informed by sharjah government to cancel his Visit Visa, i am trying to get this issue resolved since 3 weeks and havent got any positive feedback from the travel agency.
