Incompetence and lack of customer focus

Iv been with momentum since November 2018, using their comprehensive car insurance. When you first take their product they have time to sell to you but once you've bought into it they dont have time, you just another debit order. Since December 14 2018 I've been sitting waiting for management or someone to come back to me with answers for a query i had sent through regarding them correcting my policy details. I've mailed numerous times, and i call to leave messages to be contacted but still today almost 2 months later i have not been attended. Momentum has no costumer focus whatsoever .
