Loss of use of Grandfather Clock after being transported

They wrapped my grandfather clock, and made it safe to transport from Johannesburg to the Western Cape. As they wrapped it they are responsible for any damage. On arrival the pendulum mounting mechanism was snapped because of incorrect securing method. That was November 2021, now in April 2022 I am still waiting for them to repair it. I get stories like we are sending the part to Johannesburg, then part is back from Johannesburg, then it breaks again. We are sending to a local clockmaker, then from the owner, we are sending it to Johannesburg. So many different stories they cannot be trusted. Other items which they covered with their blankets for transit had minor damage as well.
