Fax 2 email not working for a week

On 28 January 2016 a I realised I was not getting my fax 2 emails. This is a very important part of my business. I Called the call centre twice and was cut off in the middle of my call TWICE. I then interacted with the Facebook tech, who tried to help and couldn't so referred me back to the help desk.<br> I sent 2 emails on their website. Both received automated responses. Neither received any other feedback.<br> I called the call centre on 2 February. Two people tried to assist me (this took a lot of my time) but couldn't. Said a tech call would be scheduled for the NEXT DAY. I threw my toys, told them my whole business is on hold. A manager then promised to try to fit me higher in the queue.<br> In the afternoon I got a call to say they had realised now that the fault is indeed on their side and they are working on it. Now 48 hours later it is STILL NOT WORKING!<br> How can they not be able to fix it? Do they even care ? I'm shocked and infuriated by it.
