Unacceptable Lack of support

I have been trying to get support for an issue that I have been experiencing on Sage One Accounting for over two weeks. Their telephone lines are always too busy and after holding for over ten minutes, the line gets cut. The online support "live chat" platform has queues of over 30 clients and when, after hours it reaches a point when I am first in the queue the site says it needs to reconnect and I get put at the back of the queue again. On Wednesday the 17th of July I sent an email to the support team and still have not had any response. I rely on this program to run my business and with the end of the month coming up it is extremely frustrating that I have tried every method of contacting support and I have had no luck in fixing this error. Please contact me in order to fix this error.
