Do not know who to contact, as the departments push the ball to each other.

I need an ADSL speed upgrade. Called the call centre sales dept, they said my number can only go up to 4M line, I needed to speak to technical dept to test my line. Then I called the technical dept, and explained that the complex across the street has 10M line, and another company across the street has 40M ADSL line. The technical dept said I have to call sales again to ask them to send a technician to me to check my line, if possible link to another exchange server which can support higher speed. So I called sales again, guess what, they said they don't send technician so I must call the technical dept again. lol. Anyway fibre is ready at my complex, so I am looking to upgrade to fibre (telkom is not one of the fibre ISP) if my adsl line is not be able to upgrade. Still do not know who to contact at telkom for a upgrade, lol.
