poor service and false information

budget insurance ordered me to take my car to renewIT edenvale on the 28th january 2016, to date im still waiting for my car. i am pregnant, i now have to depend on public transport because courtesy car expired on the 28th feb, renew IT once sent a report that parts have arrived and my car will be ready on the 08th. even today im still waiting. they are no longer communicating. i dont know what to do anymore. i was suprised when glasfit called me last week thursday saying they want to deliver my glass. why would glasfit contact me instead of renew IT and budget insurance company. something is not right. please help urgently.
