Intermittent connection for 3 days now

I work from home online and rely heavily on a steady internet connection for all my work, for the past 2 days I have had virtually no internet connection, and when i have had connection kit has being very very slow I have opened numerous tickets with amobia sent numerous e mails phoned quite a few times I have had no response from the e mails I have sent other than a automated reply and the only response I have gotten when I have phoned the support esk is that someone will look into it and get back to me well no one has gotten back to me or let me know what is going on, I am fed up with amobia all is good until there is an issue then the service is beyond dreadful I experienced better service with telkom and would go back to telkom if they had service in my area I am currently debating whether or not to look around for a new ISP as my livelihood depends on a strong internet connection, I AM LOSING MONEY AND CLIENTS DUE TO AMOBIA'S LACK OF CUSTOMER SERVICE AND DISREGARD FOR THEIR CLIENTS WELL BEING
