Closing calls when notihing has been done 12 references encounting for same issue

We have been struggling since 28th November to get Eskom to come out and assist with a fuse that came loose on the transformer. Since then we have been constantly calling and logging calls. Each time we call they give a different excuse why the call has been closed if nothing was even done. The technicians keep on informing that the fault has been sorted out and then closes the call. We are sitting with 12 references for calls that has been logged for the same issue.
