Air India — Harassment and Refund complaint

Dear Sir/Ma’am
I would like to bring to your kind notice that I have all the verified documents i.e visa, boarding pass but I couldn’t fly due to Air India airlines as they told you don’t have verified documents and we talk to embassy they told your documents are alright .They even harassed us and our ticket got wasted and with the same documents we have travelled with Emirates. Such a disgusting airlines it is and the staff members are so rude .I request you to refund my whole amount as the fault is from there side . Attaching the documents herewith
