MFC - ATROCIOUS SERVICE

I contacted MFC on 1 Dec 2022 to request a duplicate Natis document. I received a mail informing me of the necessary documents need and proof of payment. On 4 Dec I mailed all documentation to the mail addresses provided. Subsequently I have been trying to get hold of ANYONE at MFC, as the mails bounced back and there is no reply to my mails or phone calls. Today I have contacted them 4 times already and not 1 MFC employee has tried to contact me. It is imperative to have these documents before the 15th. I would expect that an institution of that magnitude would taker their customer service seriously, but CLEARLY they DONT CARE !!!!
