Faxes: downloading as TIFF File instead of PDF

Hi, I received two faxes. Logged into my RingCentral account to view the fax. When I click on the icon to open the fax, it does not open as a .PDF. I get an error message because it is trying to open as as a .TIF. RingCentral no longer allows me to get customer service over the phone (they have a number, but when you go through IVR prompts, it eventually tells you that you need to go online to get Chat support and that it is it, it just dead ends). So I went on Chat. After more than 1 hour later and rep still had not idea how to solve the problem (actually very little progress had been made as there was just delay after delay in the reps response). They told me this had to go to level 2 and that they would get back to me within 24 to 48 hours. I cant wait that long. A supervisor did call me back after a while, but he told me he could not help me. He also told me that they would send to level 2. I demanded to speak with someone and they tried to put me through to a level 2 so that they could help me. But they could not reach anyone on level 2, so they told me that will have to call me back when they can. CAN ANYONE TELL ME HOW TO RESOLVE THIS ISSUE. I am an experiences user of the faxes on RingCentral, and this has never happen before. Ring Central originally told me that to fix it that I needed to tell the customer to call send the fax again and this time to select .PDF as the file format that he was sending in. However, I told the rep that you don't actually select a file format when sending a fax. CAN ANYONE PLEASE HELP ME FAST AS I NEED ACCESS TO THESE TWO FAXES THAT CAME IN AND MY CUSTOMER CANNOT RESEND.
