No service

I have tried to call Telekom for more than 3 weeks due to not having internet abs receiving any calls. As a company we loosing because we can't make neither receive any call n they never sent anyone to come help us. They only did that when we had only accessing Internet and it never worked anywayanyway. We called on Monday n Tuesday and they said they gonna send people out urgently but no one came. We now facing difficulties.
