Oman Visa Cancellation Stamp

Dear Sir,

I was in employment from 2011 till 2014 in one of the companies in Oman. I had given 30 days notice as per my employment cpntract which was not accepted by the management and i had to leave the country without cancelling the visa. Currently i am in need of Local  PCC for my immigration purpose and for Oman i need cancellation visa stamp on my passport for PCC processing. Its 2017 and i have almost 3 years outside Oman. How can i get the cancellation stamp without contacting my previous employer? If i apply for a Visit Visa can i get that now? If i personally visit there can i get it cancelled at the airport? Even i hold the Original resident card till now. Please guide me
