Call Centre Unreachable

<p>Good day,</p> <p> </p> <p>I have been phoning your call centre for over a week trying to reach the relevant department for line transfers as I am moving to another flat within the complex that I currently reside, but every time I phone your call center the department is always "EXPERIENCING HIGH CALL VOLUMES" even after holding on for 20 minutes & more. </p> <p> </p> <p>All that I want to do is submit my application within the correct time frame to ensure that my line is available to use by the time I move into the new flat. </p>
