disgusting service

We are a business, for three weeks now, we have had ongoing Internet problems. We have been on the phone endlessly with telkom. Nobody can help! I have even taken my router to be checked at telkom. He said <br> it's working. However after plugging it in again today, it is still not working. A technician can now only come out in 3 to 4 days. This is not good enough. We are trying to do a decent day of work and we are losing clients and orders because we can't confirm orders!
