Inconsiderate about Life cover claim

My Mom passed away on 25th April 2024. Took out a policy with Sanlam Sky, ***. We submitted a claim on 28th May2024. Every time we follow up, make calls we are told that they cannot pick up the policy. My mom's policy schedule was sent to Sanlam but still they cannot pick up the claim. Sanlam however deducts the premium which at the start of the policy was R61, it has now changed to R66 which my mom took out in 2007. The cover amount of R5000 should therefore change because Sanlam has now breached the agreement that the premium will remain the same. I want to urge people to be careful on conducting business with Sanlam, they do not care about your loved ones that entrusted them with taking care of their loved ones when they are no longer there.
