Frustrated Business Client!!!

I have been having a problem with my internet account from Monday, 13/04/15. I have been calling everyday since then to get the issued resolved as i am paying for the service! Each time i call the telkom business line, not only do i spend approximately an hour each call, telkom cuts my call! the internet account is for a business and the business is dependent on the internet hence i have had downtime for the ENTIRE WEEK!!! I have been nothing but patient with telkom and this has really been frustrating as the problem is STILL NOT RESOLVED! They keep telling me that the problem has been escalated each time but there is no result and the problem is on their end as i cannot access my account! BAD SERVICE!!!
